C. Hueck et al., SEQUENCES OF CCPA AND 2 DOWNSTREAM BACILLUS-MEGATERIUM GENES WITH HOMOLOGY TO THE MOTAB OPERON FROM BACILLUS-SUBTILIS, Gene, 143(1), 1994, pp. 147-148
A regulatory gene with 69% nucleotide sequence identity to the Bacillu
s subtilis ccpA was cloned from Bacillus megaterium by complementation
of a mutant relieved of catabolite repression. Sequencing of the gene
and its adjacent regions revealed two additional open reading frames
(ORFs) downstream from ccpA. These three genes are presumably in one o
peron. ORF1 and ORF2 show homology to two genes downstream from ccpA i
n B. subtilis, as well as to the B. subtilis motA and motB genes, resp
ectively.
