3.A.1.1.3
Glycerol-phosphate porter. Transports both glycerol-3-P and glycerol-3-P diesters including glycerophosphocholine but not glycerol-2-P (Yang et al. 2009; Wuttge et al. 2012).  UgpB (the receptor) binds glycerol 3-P with high affinity, but not glycerol 2-P (Wuttge et al. 2012).  UgpB (the receptor) binds glycerol 3-P with high affinity, but not glycerol 2-P (Wuttge et al. 2012).
