Abstract

The presence or absence of some enzymes of nucleotide metabolism has been suggested by other workers as being of possible value as criteria for some genera within the . We assayed subcellular fractions of subsp. strain Y and 960 (T = type strain) for these activities. 960 had characteristics similar to those noted previously (Williams and Pollack, Int. J. Syst. Bacteriol. 35:227-230, 1985) for some other species in the in that it (i) does not show a deoxyuridine triphosphate nucleotidohydrolase, (ii) does possess deoxycytidine deaminase, (iii) does not show a specific deoxyuridine monophosphate phosphatase, and (iv) does possess deoxycytidine monophosphate deaminase. differs from these other members of the in that it (i) does possess a deoxyuridine triphosphate nucleotidohydrolase and (ii) does not show deoxycytidine or cytidine deaminase activity, but it is similar in that it does not show a specific deoxyuridine monophosphate phosphatase and does possess deoxycytidine monophosphate deaminase. Extracts of were fractionated and assayed for activities of a range of enzymes of nucleotide metabolism. Our results indicate a capacity for salvage pathways of nucleotide synthesis with similarities to those already proposed for and B-PG9.
