The methylmalonic acidurias are metabolic disorders resulting from deficient methylmalonyl-CoA mutase activity, a vitamin B(12)-dependent enzyme. We have cloned the gene for the cblB complementation group caused by deficient activity of a cob(I)alamin adenosyltransferase. This was accomplished by searching bacterial genomes for genes in close proximity to(More)
Escherichia coli DmsD interacts with the twin-arginine leader sequence of the catalytic sub-unit (DmsA) of DMSO reductase. DmsD was purified as a mixture of a number of different folding forms including: dimer (A); monomer (B); a minor thiol oxidized form; a heterogeneously folded or multi-conformational monomer form which displayed a ladder of bands on(More)
