Secondary Evidence:
Sorensen KI, Hove-Jensen B. 1996. Ribose catabolism of Escherichia coli: characterization of the rpiB gene encoding ribose phosphate isomerase B and of the rpiR gene, which is involved in regulation of rpiB expression. J Bacteriol 178(4):1003-11. Medline: 8576032.

Galactose-6-phosphate isomerase is involved in the tagatose 6-phosphate pathway of lactose catabolism in bacteria. It is a heteromultimeric protein consisting of the lacA and lacB subunits in Lactococcus and Staphlyococcus bacteria. Experimental evidence has indicated that expression of both LacA and LacB is required to obtain galactose-6-phosphate isomerase activity.

Ribose-5-P isomerase (rpi) is involved in the nonoxidative branch of the pentose phosphate pathway. Although E.coli contains both rpiA and rpiB, both enzymes are not necessary for catalyzing the isomerization step, indicating that one copy of rpi is sufficient. (Sorensen and Hove-Jensen. 1996.).

All other bacteria surveyed appear to have only one copy of ribose 5-phosphate isomerase.

Blast Summary:  PSI-Blast Search
Several hits in gapped BLAST to lacA-related proteins, e.g. residues 4-150 are 43% similar to the enzyme from M.tuberculosis. Residues 5-151 are 40% similar to MG396, a predicted lacA/rpiB galactoside acetyltransferase. Other similarities involve hypothetical proteins and predicted phosphoriboisomerase B proteins (rpiB), e.g. residues 2-153 are 36% similar to RPIB_ECOLI. No significant similarities to T.pallidum or C.trachomatis.
