Arginine catabolism by strains of oral streptococci

APMIS. 1990 Nov;98(11):1045-52. doi: 10.1111/j.1699-0463.1990.tb05033.x.

Abstract

Arginine catabolism via the arginine deiminase pathway was found in Streptococcus sanguis 903. Citrulline and ornithine were released from resting cells incubated with arginine, arginine-containing peptides, or saliva. Maximum arginine catabolism by resting cells of S. sanguis 903 was found in the pH range 7-8 and at 45-48 degrees C. Arginine deiminase activity was found in the cytoplasm and in the cell-wall extract of this strain, while ornithine carbamoyltransferase activity was found in the cytoplasm and in extracts of cell walls and cytoplasmic membranes. Streptococcus mutans GS-5 and Streptococcus sobrinus strains OMZ 176 and 6715 could release arginine from salivary peptides but were incapable of significant arginine catabolism.
