Protein Family Models

This family includes class II aldolases and adducins which have not been ascribed any enzymatic function. [1]. 8515438.

Catalyzes the isomerization of L-ribulose 5-phosphate to D-xylulose 5-phosphate in the anaerobic catabolism of L-ascorbate; links the arabinose metabolic pathway to the pentose phosphate pathway and allows the bacteria to use arabinose as an energy source

L-ribulose-5-phosphate 4-epimerase catalyzes the interconversion of L-ribulose 5-phosphate (LRu5P) and D-xylulose 5-phosphate (D-Xu5P) via a retroaldol/aldol mechanism (carbon-carbon bond cleavage analogous to a class II aldolase reaction)

E. coli has two genes, sgaE and sgbE (YiaS), that are very close homologs of araD, the established L-ribulose-5-phosphate 4-epimerase of E. coli. SgbE, part of an operon for L-xylulose metabolism, also has L-ribulose-5-phosphate 4-epimerase activity; L-xylulose-5-phosphate may be converted into L-ribulose-5-phosphate by another product of that operon. The homolog to this family from Mycobacterium smegmatis is flanked by putative araB and araA genes, consistent with it also being araD.
