Mutational analysis of genes of the mod locus involved in molybdenum transport, homeostasis, and processing in Azotobacter vinelandii.

Journal of bacteriology - 1 Sept 1995

Mouncey N J, Mitchenall L A, Pau R N

Abstract excerpt

DNA sequencing of the region upstream from the Azotobacter vinelandii operon (modEABC) that contains genes for the molybdenum transport system revealed an open reading frame (modG) encoding a hypothetical 14-kDa protein. It consists of a tandem repeat of an approximately 65-amino-acid sequence that is homologous to Mop, a 7-kDa molybdopterin-binding protein of Clostridium pasteurianum. The tandem repeat is...
