Genetic Characterization of Bacillus subtilis odhA and odhB, encoding 2-oxoglutarate dehydrogenase and dihydrolipoamide transsuccinylase, respectively
(1989) In Journal of Bacteriology 171(7). p.3667-3672- Abstract
- The 2-oxoglutarate dehydrogenase complex consists of three different subenzymes, the E1o (2-oxoglutarate dehydrogenase) component, the E2o (dihydrolipoyl transsuccinylase) component, and the E3 (dihydrolipoamide dehydrogenase) component. In Bacillus subtilis, the E1o and E2o subenzymes are encoded by odhA and odhB, respectively. A plasmid with a 6.8-kilobase-pair DNA fragment containing odhA and odhB was isolated. Functional E1o and E2o are expressed from this plasmid in Escherichia coli. Antisera generated against B. subtilis E1o and E2o expressed in E. coli reacted with antigens of the same size from B. subtilis. The nucleotide sequence of odhB and the terminal part of odhA was determined. The deduced primary sequence of B. subtilis E2o... (More)

The nucleotide sequence of odhB and the terminal part of odhA was determined. The deduced primary sequence of B. subtilis E2o shows striking similarity to the corresponding E. coli protein, which made it possible to identify the lipoyl-binding lysine residue as well as catalytic histidine and aspartic acid residues. An mRNA of 4.5 kilobases hybridizing to both odhA and odhB probes was detected, indicating that odhA and odhB form an operon. (Less)
