Several monobactams reacted with the serine dd-peptidases of Streptomyces R61 and Actinomadura R39 in a manner similar to that of bicyclic penicillins and cephalosporins. The dissociation constants of the Michaelis complexes formed between the R61 enzyme and sulfazecin (32 μM) and between the R39 peptidase and SQ 26324 (0.35 μM) had the lowest values ever observed with any β-lactam compound, suggesting an excellent fit of these two monobactams with the active sites of the respective enzymes. Azthreonam had a very poor inactivating potency, confirming its high selective reactivity towards the penicillin binding protein No. 3 of Escherichia coli. The Zn2+dd-peptidase (from Streptomyces albus G) had a high intrinsic resistance to β-lactam compounds whether they possessed a mono- or a bicyclic structure. [less ▲]

Binding of penicillin to the DD-carboxypeptidase of the unstable spheroplast L-form of Proteus mirabilis results in the rapid formation of a modified enzyme-inhibitor complex which in turn undergoes rapid decay into reactivated enzyme and an antibiotically inactive penicillin degradation product. Major antibiotic metabolites recovered from such interactions were benzylpenicilloic acid and phenoxymethylpenicilloic acid from benzylpenicillin and phenoxymethylpenicillin, respectively, suggesting a second enzymic function of the DD-carboxypeptidase as a penicillinase of low efficiency. Statistical analyses made with the help of a linear regression program show that the enzyme interacts with the substrate UDP-N-acetylmuramoyl-L-alanyl-D-gamma-glutamyl-(L)-meso-2,6-diaminopimelyl -(L)-D-alanyl-D-alanine and either benzympenicillin or carbenicillin in a non-competitive manner.

While verbal short-term memory (STM) has received considerable research interest, STM for music has been given considerably less attention. The aim of this study is to show that STM for musical stimuli is grounded in LTM, as has been shown for verbal STM. Interactions between LTM and musical STM were studied by exploring the impact of musical knowledge and musical expertise on STM performance. The role of musical knowledge was investigated by an implicit musical learning task, where participants were incidentally exposed to a sequence of tones whose succession was governed by an artificial musical grammar; after exposure, a musical STM task was presented where participants had to reproduce tone sequences of increasing length, half of the sequences being legal (obeying to the artificial musical grammar of the incidental learning task). The role of musical expertise was explored by administering the same task to two participant groups: adults with no musical training and adult musicians. For the role of newly acquired musical knowledge, the non-musician participants showed a significant advantage for reproducing legal musical sequences, showing that they had incidentally learned new musical knowledge and that this knowledge supports STM performance. The musicians did not present an incidental musical learning effect in STM recall, but overall outperformed the non-musicians for reproducing both legal and illegal tone sequences, showing an overall effect of musical expertise. This study is the first to document STM-LTM interactions in the musical domain, and this for both new and existing musical knowledge. [less ▲]

Normal and neoplastic cells interact with laminin via a variety of cell surface proteins. The specific binding sites on laminin for each particular cell surface laminin-binding protein have not yet been identified. In this study, the interaction between laminin and the high affinity metastasis-associated 67 kD laminin receptor (67 LR) was investigated by electron microscopy using the rotary shadowing technique. Laminin receptor that was purified from human colon carcinoma metastases appeared as a globular structure with a diameter of 5.2 +/- 0.8 nm. The 67 LR specifically bound to laminin on its long arm close to the intersection of the long and the short arms. There was no specific interaction of bovine serum albumin with laminin. Biochemical confirmation of the rotary shadowing experiments included slot blot solid phase assays in which [I125]-labeled 67 LR bound in a dose dependent manner to laminin as well as to the chymotrypsin resistant (C1) fragment of laminin that contains a short piece of the long arm. [I125]-labeled 67 LR did not bind to the pepsin resistant (P1) fragment of laminin that did not contain that segment on the long arm. This study therefore identifies the binding site on laminin for the 67 kD metastasis-associated laminin receptor as a region on the long arm of laminin close to the intersection of the four arms.

The interaction between the exocellular DD-carboxypeptidase-transpeptidase of Streptomyces R61 and beta-lactam antibiotics is a multistep process during which a rather stable enzyme - antibiotic complex is formed. This mechanism of interaction is compatible with Lineweaver-Burk plots that are typical of a competitive inhibition of the hydrolysis of the peptide donor by the antibiotic. In fact, however, the same Lineweaver-Burk plots can be obtained on the basis of a non-competitive type of inhibition. At present, a choice between the two models cannot be made. [less ▲]

We screened a cDNA bank of rabbit gastric fundic mucosa by two-hybrid assays looking for binding partners of the N-terminal domain of the rabbit gastric H,K-ATPase. We extracted five clones sharing more than 90% sequence identity. The longest clone codes for a protein sharing a high identity (96 and 96.8%, respectively) with a fragment of the membrane domain, from Arg-835 to Ser-873, plus the major part of the "spectrin binding domain" going from Glu-874 to Leu-1455 of human and mouse ankyrin III. We conclude that the membrane and spectrin binding domains of the rabbit ankyrin III are candidates for the binding partner of the N-terminal domain of the rabbit gastric H,K-ATPase. To validate the ankyrin-ATPase interaction and to test its specificity, we produced both domains in yeast and bacteria, coimmunoprecipitated them with an anti-ATPase antibody, and copurified them by affinity chromatography. The sequence of rabbit ankyrin III was not known, and this is the first report demonstrating that the ankyrin III and the H,K-ATPase interact with no intermediate. The interaction involves the N-terminal domain of the ATPase on one hand and the spectrin binding domain of the ankyrin on the other. [less ▲]

The murein (peptidoglycan) sacculus is an essential polymer embedded in the bacterial envelope. The Escherichia coli class B penicillin-binding protein (PBP) 3 is a murein transpeptidase and essential for cell division. In an affinity chromatography experiment, the bifunctional transglycosylase-transpeptidase murein synthase PBP1B was retained by PBP3-sepharose when a membrane fraction of E. coli was applied. The direct protein-protein interaction between purified PBP3 and PBP1B was characterized in vitro by surface plasmon resonance. The interaction was confirmed in vivo employing two different methods: by a bacterial two-hybrid system, and by cross-linking/co-immunoprecipitation. In the bacterial two-hybrid system, a truncated PBP3 comprising the N-terminal 56 amino acids interacted with PBP1B. Both synthases could be cross-linked in vivo in wild-type cells and in cells lacking FtsW or FtsN. PBP1B localized diffusely and in foci at the septation site and also at the side wall. Statistical analysis of the immunofluorescence signals revealed that the localization of PBP1B at the septation site depended on the physical presence of PBP3, but not on the activity of PBP3. These studies have demonstrated, for the first time, a direct interaction between a class B PBP (PBP3) and a class A PBP (PBP1B) in vitro and in vivo, indicating that different murein synthases might act in concert to enlarge the murein sacculus during cell division.
