3-dehydro-L-gulonate-6-phosphate decarboxylase  M-CSA #236

3-keto-L-gulonate 6-phosphate decarboxylase (KGPDC), isolated from Escherichia coli, catalyses the decarboxylation of 3-keto-L-gulonate 6-phosphate to L-xylulose 5-phosphate and carbon dioxide. KGPDB is a member of the orotidine 5'-monophosphate decarboxylase suprafamily, in that it shares a common active site architecture but not substrate specificity or mechanism. KGPDC is promiscuous and can also catalyse a low level of the D-arabino-hex-3-ulose 6-phosphate synthase (HPS) reaction: D-ribulose 5-phosphate and formaldehyde to D-arabino-hex-3-ulose 6-phosphate.

KGPDC exists as a homodimer with two active sites. Residues from both subunits can be found in each active site.
