uidC - Putative outer membrane porin for beta-glucuronides porin protein; Enhances the activity of the UidB (GusB) glucuronide transporter, on its own however it has no transport activity. Glucuronide transport does not occur in strain K12 due to a variant at position 100 of the UidB (GusB, AC P0CE44, AC P0CE45) protein. [a.k.a. b1615, AAC74687.2, WP_001227023.1]

tsx - Nucleoside channel, receptor of phage T6 and colicin K; Functions as substrate-specific channel for nucleosides and deoxynucleosides. Has a greater affinity for deoxynucleosides than for nucleosides, and does not transport free bases. In addition, constitutes the receptor for colicin K and phage T6.

degS - Serine endoprotease, periplasmic; A site-1 protease (S1P) that cleaves the peptide bond between 'Val-148' and 'Ser-149' in RseA. Part of a regulated intramembrane proteolysis (RIP) cascade. When heat shock or other environmental stresses disrupt protein folding in the periplasm, DegS senses the accumulation of unassembled outer membrane porins (OMP) and then initiates RseA (anti sigma-E factor) degradation by cleaving its periplasmic domain, making it a substrate for subsequent cleavage by RseP. This cascade ultimately leads to the sigma-E-driven expression of a variety of factors deal [...] [a.k.a. b3235, AAC76267.1, Q2M8X8]
