HPrK regulates succinate-mediated catabolite repression in the gram-negative symbiont Sinorhizobium meliloti.
The HPrK kinase/phosphatase is a common component of the phosphotransferase system (PTS) of gram-positive bacteria and regulates catabolite repression through phosphorylation/dephosphorylation of its… Expand
Sinorhizobium meliloti mutants lacking phosphotransferase system enzyme HPr or EIIA are altered in diverse processes, including carbon metabolism, cobalt requirements, and succinoglycan production.

Bacteriological Examination of Waters: Membrane Filtration Protocol
The membrane filtration technique is used to examine water samples from different sources. The membrane is incubated on an agar plate. Bacterial (and other) cells trapped on the membrane will grow… Expand
