Peptide and amino acid transport in Streptococcus bovis

In amino acid transport studies with Streptococcus bovis using 14C-labelled amino acids, it has been shown that between 87% and 95% of cell-associated radioactivity was located in the cytosol. In similar studies with unlabelled peptides, most test peptide associated with S. bovis was truly intracellular. Using sodium dodecyl sulphate-polyacrylamide gel electrophoresis, the proteolytic activity in S. bovis was found to be largely cell-associated and of the serine-protease type, but stimulated by… CONTINUE READING
