PFAM accession number:PF06026
Interpro abstract (IPR004788):

Ribose 5-phosphate isomerase, also known as phosphoriboisomerase, catalyses the reversible conversion of D-ribose 5-phosphate to D-ribulose 5-phosphate, the first step in the non-oxidative branch of the pentose phosphate pathway [(PUBMED:12517338)]. This reaction enables ribose to be synthesized from sugars, as well as the recycling of sugars during the degradation of nucleotides. There are two unrelated types of ribose 5-phosphate isomerases: type A (RpiA) is the most common and is found in most organisms, while type B (RpiB) is restricted to specific eukaryotic and prokaryotic species. Escherichia coli produces both RpiA and RpiB (also known as AlsB), although RpiA accounts for 99% of total RPI enzymes [(PUBMED:12211039)].

This entry represents type A (RpiA) enzymes found in eukaryotes (plants, Metazoa and fungi), bacteria and archaea.

GO process:pentose-phosphate shunt, non-oxidative branch (GO:0009052)
