Function
Characterized members of this family possess 15-18 transmembrane segments (TMSs) and are roughly 460-565 amino acyl residues in length.
General transport reaction
Transport reactions catalyzed by functionally characterized members of the LctP family include:[2]
D- or L-lactate or glycolate (out) + H+ (out) → D- or L-lactate or glycolate (in) + H+ (in).
