Description

Bacillus subtilis contains three classes of 6-phosphogluconate dehydrogenases (6PGD), including Gnd (YqjI), GntZ and YqeC. This entry represent the YqeC class, which in B. subtilis is a truncated 6PGD that possesses a NAD+-dependent activity [PMID: 15231785].

YgeC class of 6PGD includes prokaryotic proteins similar to the bacterial and eukaryotic 6PGD but differs from it by a deep split in a UPGMA similarity clustering tree and the lack of a central region of about 140 residues. This truncated 6PGD can be found in most Gram-positive organisms, such as Bacillus subtilis and Mycobacterium tuberculosis. The protein from Methylobacillus flagellatus KT has been characterised as a decarboxylating 6-phosphogluconate dehydrogenase as part of an unusual formaldehyde oxidation cycle [PMID: 10658669]. This entry also includes Pseudomonas fluorescens 6PGD, which is active with either NAD+ and NADP+ [PMID: 6402366], and Streptomyces and heterofermentative lactic acid bacteria 6PGD, which has the NAD+-dependent activity [PMID: 3208200, PMID: 8829540].
