3.A.1.5.41
Oligopeptide transporter, OppABCDF/MppA/YgiS.  MppA is a murein peptide receptor, and YgiS is a bile acid (e.g., cholate, deoxycholate) receptor that may use the Opp system for uptake.  YgiS mRNA is degraded by the toxin MgsR which is regulated by the antitoxin, MgsA and this loss of the mRNA protects the cell against bile acid stress (Kwan et al. 2015).
