3.A.1.12.16
Glycine betaine/carnitine/choline/proline transporter, OpuABC. It is not a dominant proline transporter which in S. aureus are, however, PutP and ProT (Lehman et al. 2023). The sequence of OpuB, the membrane component of the system, is not included here. The 3-d structure of OpuC (or a part of it) has been solved (5IIP_A-D). .
