Protein Domain : IPR020672

Name  Ribose-5-phosphate isomerase, type A, subgroup Short Name  Ribose5P_isomerase_typA_subgr
Type  Family Description  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 []. 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 coliproduces both RpiA and RpiB (also known as AlsB), although RpiA accounts for 99% of total RPI enzymes []. This entry represents a subgroup of type A ribose-5-phosphate isomerase that is found in bacteria, archaea and eukaryotes (plants and Metazoa), but excluding those found in fungi.
