Regulation of glutamine synthetase by metal-catalyzed oxidative modification in the marine oxyphotobacterium Prochlorococcus.

The inactivation of glutamine synthetase (GS; EC 6.3.1.

In vivo regulation of glutamine synthetase activity in the marine chlorophyll b-containing cyanobacterium Prochlorococcus sp. strain PCC 9511 (oxyphotobacteria).

The physiological regulation of glutamine synthetase (GS; EC 6.3.1.

Cloning of an ORF with homology to Mycobacterium echA1, encoding the enoyl-CoA hydratase, in Rhodococcus fascians.

An open reading frame encoding a polypeptide of significant homology (55.7% identity) with the enoyl-CoA hydratase encoded by the gene echA1 from Mycobacterium tuberculosis has been found in the genome of the plant-pathogen bacteria Rhodococcus fascians strain NRRL-B-15096. Sequence alignments showed that it possesses several conserved blocks common to E.

Purification and characterization of limonoate dehydrogenase from Rhodococcus fascians.

Limonoate dehydrogenase from Rhodococcus fascians has been purified to electrophoretic homogeneity by a procedure that consists of ion-exchange, hydrophobic, and affinity chromatography. The native enzyme has a molecular mass of around 128,000 Da and appears to be composed of four similar subunits (30,000 Da each). The isoelectric point is 4.
