Isolation and characterization of draT mutants that have altered regulatory properties of dinitrogenase reductase ADP-ribosyltransferase in Rhodospirillum rubrum.

Microbiology (Reading, England) - 1 Jan 2001

Zhang Y, Kim K, Ludden P, Roberts G

Abstract excerpt

In Rhodospirillum rubrum, dinitrogenase reductase ADP-ribosyltransferase (DRAT) is responsible for the ADP-ribosylation of dinitrogenase reductase in response to the addition of NH(+)(4) or removal from light, resulting in a decrease in nitrogenase activity. DRAT is itself subject to post-translational regulation; to investigate the mechanism for the regulation of DRAT activity, random PCR mutagenesis of draT...
