Has been implicated in selenate reduction; a mini-Tn10 insertion mutant in 'molR', (which was mapped to 47.3 centisomes i.e. this locus), is defective in the reduction of selenate. Repressed by LexA, induced by DNA damage. Was originally thought to be involved in the regulation of molybdate metabolism, which gave rise to the name molR, however the locus in PubMed:2156810 was mapped at 65 centisomes (minutes) on the E.coli chromosome, while this locus maps to 47.3 centisomes (PubMed:2156810). This locus gives rise to a transcript that could encode the 'interrupted' N-terminal 274 amino acid gene product of yehF. The protein it encodes (shown here) is missing the C-terminus compared to orthologs.
