Delighted that our FtsEX-EnvC paper is now live at mBio!
FtsEX-EnvC is a bacterial Type VII ABC transporter that activates key periplasmic enzymes during cell division.
We found mutations that disrupt FtsEX-EnvC activity and a disulfide that leaves it permanently active.

Through site-directed mutagenesis, the researchers identified mutations that disrupt the autoinhibition mechanism of FtsEX-EnvC, as well as a variant that prevents activation.

Type VII ABC transporters are unique to bacteria with important physiological functions.
Examples are the FtsEX-EnvC complex (cell division), the MacAB-TolC efflux pump (antibiotic resistance) and LolCDE-LolA (lipoprotein trafficking) system.
Here we define YbbAP-TesA as a novel esterase complex.

New preprint!
FtsEX-EnvC is a Type VII ABC transporter that activates the periplasmic enzymes needed to break the peptidoglycan layer during cell division.
We tested the importance of structural features underpinning activation and the auto-inhibition mechanism that keeps it all in check.
