The enzymes and pathways involved in the catabolism of
glucose by several strains of Streptococcus diacetilactis, Streptococcus
cremoris, and Streptococcus lactis, commonly called the
lactic streptococci, were studied. The presence of aldolase,
triosephosphate isomerase and alcohol dehydrogenase in these
organisms provided evidence for the operation of the Embden-Meyerhof-Parnas (EMP) pathway...
Phosphorylation of free galactose by lactic streptococci was
mediated by an adenosine triphosphate (ATP) dependent kinase which
was repressed by glucose. The phosphoenolypyruvate (PEP) phosphotransferase
system (PTS) was not involved in transport of galactose,
The conversion of free galactose to glucose was also demonstrated.
A key Leloir pathway enzyme, uridine...
