ribose-5-phosphate isomerase M-CSA #680 | Ribose-5-phosphate isomerase is able to catalyse the interconversion of Ribose-5-phosphate and Ribulose-5-phosphate, an isomerisation reaction involving the open chain forms of the two sugars, important in the pentose phosphate pathway. In Escherichia coli there are two forms of the enzyme, which although they catalyse the same reaction, have entirely different mechanisms and catalytic residues. The less common Escherichia coli RpiB is described here. | Defined by 5 residues: ASP:A-22 [auth A-9]CYS:A-79 [auth A-66]THR:A-81 [auth A-68]HIS:D-112 [auth D-99]HIS:D-147 [auth D-134] | EC: 5.3.1.6 (PDB Primary Data) |
