Disease relevance of Rru_A3542

Malate dehydrogenase from Rhodospirillum rubrum, Rhodobacter capsulatus and Rhodomicrobium vannielii (which are all tetrameric proteins) had an unusually high glycine content, but the enzyme from Rhodocyclus purpureus (which is a dimer) did not [1].
Malate dehydrogenase in phototrophic purple bacteria: purification, molecular weight, and quaternary structure [2].
The citric acid cycle enzyme malate dehydrogenase was purified to homogeneity from the nonsulfur purple bacteria Rhodobacter capsulatus, Rhodospirillum rubrum, Rhodomicrobium vannielii, and Rhodocyclus purpureus [2].

High impact information on Rru_A3542

Homogeneity of malate dehydrogenase preparations from the four organisms was determined by sodium dodecyl sulfate and nondenaturing polyacrylamide gel electrophoresis; a single protein band was observed in purified preparations by both techniques [2].
Malate dehydrogenase was purified from each species by either a single- or a two-step protocol: triazine dye affinity chromatography was the key step in purification of malate dehydrogenase in all cases [2].
Glutamate dehydrogenase, glutamine synthetase, glutamate synthase, malate dehydrogenase, nitrogenase, and ammonium were assayed before and after malate addition [3].
