CpeF family


Also called MpeX in Prochlorococcus marinus SS120 (Hess et al.,1999) and MpeV in marine Synechococcus spp. (Wilbanks et al., 1993, Six et al., 2007). In the latter group, it is found both in strains with a low PUB:PEB ratio and in type IV chromatic adapters, which also have MpeU. CpeF is the bilin lyase that ligates the doubly linked phycoerythrobilin on
β- phycoerythrin in Fremyella diplosiphon (Kronfel et al. 2019).
