Also known as
ECK1046
Summary
DinI inhibits RecA co-protease activity of UmuD, but not LexA. [More information is available at EcoGene: EG12670]. The dinI gene was first identified as a chromosomal locus containing a high affinity operator for the LexA repressor . [More information is available at EcoCyc: G6558].

GeneRIFs: Gene References Into Functions

What's a GeneRIF?
  1. DinI either binds to the C-terminus of a RecA protomer or DinI resides deeply in the groove of the RecA filament, with its negatively charged C-terminal helix proximal to the L2 loop of RecA.
