The walls of Nocardia kirovani are composed of three main constituents: the peptidoglycan matrix, a polysaccharide polymer and a variety of free and bound lipids. The free lipids represent 17.5% (dry weight) of the walls and consist for the major part of C16–18 fatty acids and nocardic acids, and for the minor part, of nocardones, triglycerides and carotenoid pigments. The nocardic acids were identified as tri- and tetra-unsaturated, α-branched, β-hydroxylated compounds C58H110O3—C66H124O3 the nocardones as tri-and tetra-unsaturated ketones C57H106O—C63H1180O, and the main carotenoid pigment as phlei-xantophylle palmitate. Esters of glycerol with C14, C16, C18 fatty acids and, for some of them, with odd numbered poly-unsaturated acids containing 35 to 45 carbon atoms, were also identified. Bound lipids represent about 20% (dry weight) of the walls and consist mainly of nocardic acids probably ester-linked to an arabinogalactan polymer. The peptidoglycan (about 40% dry weight) is composed of β-1,4-N-acetylglucosaminyl-N-glycolylmuramic acid disaccharide units that are substituted by diamidated L-Ala-D-αGln-(L)-A2pm-(D)-NH2 tripeptides and diamidated l-Ala-d-αGln-(L)-A2pm-(D)-NH2-(L)-d-Ala tetrapeptides, where A2pm is meso-diaminopimelic acid. Crosslinking between some of the peptide units is mediated through D-Ala-(D)-A2pm linkages (peptidoglycan of chemotype I). [less ▲]

Curves of radial displacements for alpha2 CVn are obtained by mechanical integration of radial velocity curves deduced from measures by Struve and Swings and by Babcock and Burd for EuII, CrII, FeI and II, and by Pyper for EuII.. In order to proceed to the comparison, a value as accurate as possible is sought for the period. If we take all the known photometric observations into account, we get 5.4693+-0.0001 d. Small differences between the curves for a given ion are noted, especially when using Pyper's measures. However these discrepancies do not necessarily prove the existence of secular variations; in the binary model, they can be interpreted mainly in terms of the Ovenden effect. Too large displacements, and other peculiarities in the variations, may also be attributed to that effect, and to circumstellar currents. The ranges of the velocity variations and of the radial displacements are also discussed for other Ap stars. [less ▲]

In the presence of N(alpha),N(epsilon)-diacetyl-L-Lys-D-Ala-D-Ala as donor, and either D-[(14)C]alanine, [(14)C]-glycine, or meso-[(3)H]diaminopimelic acid as acceptor, the DD carboxypeptidases from Streptomyces R61 and R39 catalyze a transpeptidation reaction with the release of terminal D-alanine from the donor and the formation of either N(alpha),N(epsilon)-diacetyl-L-Lys-D-Ala-D-[(14)C]Ala, N(alpha),N(epsilon)-diacetyl-L-Lys-D-Ala-[(14)C] Gly, or N(alpha),N(epsilon)-diacetyl-L-Lys-D-Ala-D-meso- [(3)H]diaminopimelic acid. The reaction appears to be a true transpeptidation, and is not simply a "reversal of hydrolysis". Transpeptidation is inhibited by pencillin at concentrations that inhibit hydrolysis (carboxypeptidase action) of the donor peptide. There are differences in the specificity profiles of the Streptomyces enzymes for acceptor molecules:only the R61 enzyme used [(14)C]Gly-Gly as acceptor; transfer of N(alpha),N(epsilon)-diacetyl-L-Lys-D-Ala to this acceptor resulted in the formation of N(alpha),N(epsilon)-diacetyl-Lys-D-Ala-[(14)C] Gly-Gly, with the synthesis of a (D-Ala-Gly) peptide bond in an endoposition.
