CyanoLyase

MpeU family

Description

Present only in PEII-containing marine Synechococcus. It is found both in strains with a high PUB:PEB ratio and in type IV chromatic adapters (Six et al., 2007; Mahmoud et al., 2017). Interruption of mpeU caused a reduction in PUB content, impaired phycobilisome assembly and reduced growth rate more strongly in blue than green light.(Mahmoud et al.2017). MpeU.is therefore important for adaptation of Synechococcus spp. to blue light.
