High impact information on lrtA

The core enzyme with purified a sigma factor, SigA/SigD or SigB, allowed specific in vitro transcription from the light-inducible psbA2 or the dark-/heat-inducible lrtA/hspA promoters, respectively [1].

Regulatory relationships of lrtA

Expression of the dark-induced lrtA and light-induced psbA2/3 transcript was significantly reduced in the sigB and sigD knockout strains, respectively [2].
