Function

OccD-subfamily channel PMID:28440622.
Single-channel and uptake data [PMID:22272184 "Remarkably, the conductance of the dominant state of OccD3 is the largest of all channels analyzed";
"The efficient arginine uptake mediated by OccD3 is noteworthy since this protein was shown, like OccD1, to mediate arginine uptake in P. aeruginosa in vivo"].
Operon partner of dppA4 PMID:25338022.

The term is correct (Eren 2012 single-channel and arginine uptake; PMID:28440622). PSEUDOCAP WRONG_REFERENCE, REPOINT to PMID:22272184, CONFIRMED.
