Biosynthesis of D-Aspartic Acid by Streptococcus faecalis*
In biotin deficiency, aspartic acid becomes a limiting factor in the growth of Streptococcus faecalis ATCC 9190. Suboptimal concentrations of L-aspartate in biotin-deficient medium produce partial growth followed by lysis, which is typical of cell wall lysis due to depletion of an amino acid essential for cell wall biosynthesis. D-Aspartate, which is utilized by the cells with considerable less...

متن کاملEffect of carbon dioxide on the aspartic acid requirement for proteinase biosynthesis by Streptococcus faecalis var. liquefaciens.
Non-proliferating cells of Streptococcus faecalis var. liquefaciens required aspartic acid for proteinase biosynthesis in the absence of CO(2) but not in the presence of CO(2).
متن کاملThe biosynthesis of hyaluronic acid by Streptococcus.
The mechanism of hyaluronic acid chain growth in a particulate enzyme preparation obtained from Group A Strepfococcus has been examined and additional characteristics of the enzyme detailed. Hyaluronic acid chain elongation occurs by the transfer of monosaccharide units from uridine nucleoside diphosphate derivatives to the nonreducing ends of endogenous oligosaccharide. This oligosaccharide wh...
متن کاملBiosynthesis of hyaluronic acid by Streptococcus.
Synthesis of hyaluronic acid was investigated in a cell-free system derived from a strain of Group A streptococci. Preparative procedures were improved so that an enzyme system 70 times more active than that previously reported was obtained. The hyaluronic acid synthesized could be separated into trichloroacetic acid-soluble and -insoluble fractions. On the basis of pulse-chase experiments, it ...
