CC   -!- FUNCTION: Is involved in L-lactate degradation and allows cells to grow
CC       with lactate as the sole carbon source. Has probably a role as an
CC       electron transporter during oxidation of L-lactate. {ECO:0000255|HAMAP-
CC       Rule:MF_02103}.
CC   -!- SIMILARITY: Belongs to the LutB/YkgF family. {ECO:0000255|HAMAP-
CC       Rule:MF_02103}.
