STRUCTURE OF MYCOBACTERIUM TUBERCULOSIS RIBOSE-5-PHOSPHATE ISOMERASE, RPIB, RV2465C, COMPLEXED WITH PHOSPHATE.

Overview

Ribose-5-phosphate isomerases (EC 5.3.1.6) inter-convert, ribose-5-phosphate and ribulose-5-phosphate. This reaction allows the, synthesis of ribose from other sugars, as well a means for salvage of, carbohydrates after nucleotide breakdown. Two unrelated types of enzyme, are known to catalyze the isomerization. The most common one, RpiA, is, present in almost all organisms. The second type, RpiB, is found in many, bacterial species.Here, we demonstrate that the RpiB from Mycobacterium, tuberculosis (Rv2465c) has catalytic properties very similar to those, previously reported for the Escherichia coli RpiB enzyme. Further, we, report the structure of the mycobacterial enzyme, solved by molecular, replacement and refined to 1.88A resolution. Comparison with the E.coli, structure shows that ...
