Laminin promotes cerebellar granule cells migration in vitro and is synthesized by cultured astrocytes

Newborn rat cerebellum microexplants have been used as a model to study neuronal migration. Laminin in a substrate-bound form modifies extensively the migratory behavior of the neurones, an effect which is blocked if antilaminin antibodies are present during the assay. 35S methionine incorporation followed by SDS-PAGE electrophoresis, fluorography and immunoprecipitation with antilaminin antibodies allowed to demonstrate that laminin is synthesized and secreted by cultured newborn rat cerebellum as well as by cultured newborn rat cerebral cortex astrocytes.

The beta-lactamase of Enterobacter cloacae P99 consists of one polypeptide chain of Mr 39000 devoid of disulphide bridges and free thiol groups. It contains an unusually high proportion of tyrosine and tryptophan. The N-terminal sequence exhibits overlaps with the tryptic peptide obtained after labelling the active site with 6 beta-iodopenicillanate. The active-site serine residue is at position 64. The homology with the chromosomal beta-lactamase of Escherichia coli K 12 (ampC gene) is lower within the 25 residues of the N-terminal portion than around the active-site serine residue. The P99 beta-lactamase is inactivated by 6 beta-bromo- and 6 beta-iodo-penicillanate, with a second-order rate constant of 110-140M-1 X s-1 at 30 degrees C and pH 7.0, a value that is much lower than that observed with class-A beta-lactamases.
