Regulated Operon: pdhABCD

Genes
Genes Synonyms Direction Genome position Function COG ID Genus clusters
pdhA aceA + 1527633..1528748 pyruvate dehydrogenase (E1 alpha subunit) COG1071 pdhA-BAC pdhA-STA aceA-BAC  
pdhB
+ 1528752..1529729 pyruvate dehydrogenase (E1 beta subunit) COG0022  
pdhC
+ 1529844..1531172 pyruvate dehydrogenase (dihydrolipoamide acetyltransferase E2 subunit) COG0508 pdhC-BAC  
pdhD citL + 1531177..1532589 dihydrolipoamide dehydrogenase E3 subunit of both pyruvate dehydrogenase and 2-oxoglutarate dehydrogenase complexes COG1249  

Operon evidence: Northern blotting (5.2 kb transcript)
Reference: Hemila H, et al. (1990), Gao H, et al. (2002)
Comments: Hemila also found a 2.8 kb pdhCD and a 1.7 kb monocistronic transcript. However, Gao et al. note that promoters were found in front of pdhA and pdhC only; no promoter was found in front of pdhD.
