The gene convergent to luxG in Vibrio fischeri codes for a protein related in sequence to RibG and deoxycytidylate deaminase.
The nucleotide sequence of a convergent gene with the same bidirectional transcriptional terminator as the Vibrio fischeri lux operon has been determined. This gene codes for a polypeptide of 147 amino acids which is related in sequence to the polypeptide coded by the first gene (ribG) of the rib operon of Bacillus subtilis as well as deoxycytidylate deaminase of T4 bacteriophage and Saccharomyces cerevisiae. These results raise the possibility of a linkage between the regulation of the lux genes and riboflavin synthesis in Vibrio fischeri.
