Folate reductase and specific dihydrofolate reductase activities of the amethopterin-sensitive Streptococcus faecium var. durans.
Preliminary evidence is presented that indicates that the dihydrofolate reductase activity of amethopterin-sensitive Streptococcus faecium var. durans ATCC 8043 is separable into two dihydrofolate reductases, one of which also reduces folate.
متن کاملDihydrofolate Reductase of Streptococcus f aecium II. PURIFICATION AND SOME PROPERTIES OF TWO DIHYDROFOLATE REDUCTASES FROM THE AMETHOPTERIN-RESISTANT
From a single amethopterin-resistant organism, Streptococcus faecium var. durans strain A, two different dihydrofolate reductases have been obtained as essentially homogeneous proteins in good yield. One of the reductases has a similar substrate specificity and turnover number (about 8000 moles per min per mole of enzyme) to the single reductase found in the amethopterin-sensitive strain of S. ...

متن کاملSusceptibility of various serogroups of streptococci to clindamycin and lincomycin.
The minimal inhibitory concentration of lincomycin and clindamycin for a large number of strains from multiple serogroups of streptococci was determined. The median minimal inhibitory concentration for streptococci from groups A, B, C, F, G, H, L, and M and nongroupable organisms ranged from 0.02 to 0.39 mug of lincomycin per ml and from </=0.01 to 0.09 mug of clindamycin per ml. Among the grou...
