Crude cell-free extracts of some strains of each L. casei and L. plantarum were assayed for their amino-, imino- and endopeptidase as well as the caseinolytic activity. L-alanine-, L-phenylalanine- and L-leucine-p-nitroanilide but not L-glutamic acid-p-nitroanilide, were hydrolyzed by all the strain
Phosphoenolpyruvate carboxykinase (PEPCK) was purified 600-fold to homogeneity from the cotyledons of cucumber (Cucumis sativus L.) and a polyclonal antiserum raised. After sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) the purified preparation contained a single polypeptide of
