CpcE-I subfamily


Forms a heterodimer with CpcF-I. The CpcE-I/CpcF-I complex attaches a PCB at cys-84 of alpha-PC (Fairchild et al., 1992; Swanson et al. 1992; Bhalerao et al. 1994; . The crystal structure of the heterodimer of CpcE-I/F-I
from Nostoc sp. PCC7120 was determined at 1.89-Å resolution (Zhao et al., 2017).
