CC   -!- SUBUNIT: MCR is composed of three subunits: alpha, beta, and gamma. The
CC       function of proteins C and D is not known.
CC   -!- DEVELOPMENTAL STAGE: There are two MCR complexes in this bacteria. MCR
CC       II is expressed in the early growth phase. Late growth cells contains
CC       mostly MCR I.
