MpeW family


This group includes sequences of putative PEII:PEB lyases-isomerases that are related to MpeY and MpeZ, but sufficiently different to form another family (Humily et al., 2013). Sequence related to MpeY and MpeZ and more distantly to CpeY (Humily et al., 2013). The mpeW gene is specific of one of the two groups of marine Synechococcus able to chromatically acclimate (CA4-B) and is located in a genomic subregion of the large phycobilisome rod region specifically involved in CA4.
