PROVISIONAL
Organism
Escherichia coli str. K-12 substr. MG1655 (strain: K-12, substrain: MG1655)
Lineage
Bacteria; Pseudomonadota; Gammaproteobacteria; Enterobacterales; Enterobacteriaceae; Escherichia
Also known as
ECK4170; hflA; hslY
Summary
Gain-of-function alleles in hflC and hflK inhibit FtsH-mediated degradation of uncomplexed SecY protein and other membrane protein substrates. [More information is available at EcoGene: EG10436]. The HflK-HflC (HflKC) complex interacts with FtsH and regulates (inhibits) proteolysis by FtsH of SecY and lambda cII protein . [More information is available at EcoCyc: EG10436].

What's a GeneRIF?
  1. HflKC inhibits the proteolysis of lambdaCII by HflB and hence the overexpression of the former results in an increase in the lysogenic frequency.
    Title: Studies on Escherichia coli HflKC suggest the presence of an unidentified λ factor that influences the lysis-lysogeny switch.
  2. report the first purification of HflK and HflC separately as active and functional proteins and show that each can interact with HflB on its own and each inhibits the proteolysis of lambdaCII
    Title: Escherichia coli HflK and HflC can individually inhibit the HflB (FtsH)-mediated proteolysis of lambdaCII in vitro.
  3. These results demonstrate the importance of right-handed coiled-coil interactions in the oligomerization of HflKC, and a model entailing the formation of a right-handed helical barrel is proposed.
    Title: The periplasmic domains of Escherichia coli HflKC oligomerize through right-handed coiled-coil interactions.
