The physiology and biochemistry of the proteolytic system in lactic acid bacteria.
The inability of lactic acid bacteria to synthesize many of the amino acids required for protein synthesis necessitates the active functioning of a proteolytic system in those environments whereExpand

Fructose 1,6-diphosphate-activated L-lactate dehydrogenase from Streptococcus lactis: kinetic properties and factors affecting activation.
The L-(+)-lactate dehydrogenase (L-lactate:NAD+ oxidoreductase, EC 1.1.1.27) of Streptococcus lactis C10, like that of other streptococci, was activated by fructose 1,6-diphosphate (FDP). The enzymeExpand

Occurrence of arginine deiminase pathway enzymes in arginine catabolism by wine lactic Acid bacteria.
l-Arginine, an amino acid found in significant quantities in grape juice and wine, is known to be catabolized by some wine lactic acid bacteria. The correlation between the occurrence of arginineExpand

Arginine catabolism in wine lactic acid bacteria: is it via the arginine deiminase pathway or the arginase-urease pathway?
The wine lactic acid bacteria Leuconostoc oenos OENO and Lactobacillus buchneri CUC-3 catabolize L-arginine to ornithine and ammonia as major end-products, with 1 mole of arginine converted into 2Expand

Factors Affecting the Activity and Synthesis of NAD-dependent Lactate Dehydrogenase in Rhizopus oryzae
Summary: The NAD-dependent lactate dehydrogenase of Rhizopus oryzae, like some bacterial lactate dehydrogenases, catalyses reduction of pyruvate by NADH but not the reverse reaction. It will,Expand
