Amino Acid Sequence Around the Catalytic Site in Glyceraldehyde-3-Phosphate Dehydrogenase from Bacillus stearothermophilus.

Crystal structure of two ternary complexes of phosphorylating glyceraldehyde-3-phosphate dehydrogenase from Bacillus stearothermophilus with NAD and D-glyceraldehyde 3-phosphate.

The crystal structure of the phosphorylating glyceraldehyde-3-phosphate dehydrogenase (GAPDH) from Bacillus stearothermophilus was solved in complex with its cofactor, NAD, and its physiological substrate, D-glyceraldehyde 3-phosphate (D-G3P). To isolate a stable ternary complex, the nucleophilic residue of the active site, Cys(149), was substituted with alanine or serine. The C149A and C149S G...

The binding of nicotinamide-adenine dimucleotide to glyceraldehyde 3-phosphate dehydrogenase from Bacillus stearothermophilus.

The binding of NAD+ to glyceraldehyde 3-phosphate dehydrogenase (EC 1.2.1.12) from Bacillus stearothermophilus has been studied by measurement of protein fluorescence quenching. Slight negative co-operativity was observed in the binding of the third and fourth coenzyme molecules to the tetrameric enzyme. The first two coenzyme molecules were tightly bound. In this respect the enzyme resembles t...

A glyceraldehyde-3-phosphate dehydrogenase homolog in Borrelia burgdorferi and Borrelia hermsii.

A polyreactive monoclonal antibody recognized a 38.5-kDa polypeptide with amino-terminal sequence identity to conserved regions of glyceraldehyde-3-phosphate dehydrogenase (GAPDH) in Borrelia burgdorferi, the Lyme disease agent, and Borrelia hermsii, an agent of American relapsing fever. This monoclonal antibody also recognized GAPDH from other pathogenic spirochetes and other prokaryotes and e...

Widespread occurrence of non-phosphorylating glyceraldehyde-3-phosphate dehydrogenase among gram-positive bacteria.

The non-phosphorylating glyceraldehyde 3-phosphate dehydrogenase (GAPDHN, NADP+-specific, EC 1.2.1.9) is present in green eukaryotes and some Streptococcus strains. The present report describes the results of activity and immunoblot analyses, which were used to generate the first survey of bacterial GAPDHN distribution in a number of Bacillus, Streptococcus and Clostridium strains. Putative gap...
