MpeU family
[fasta] [only sure] [only unsure]
Description
Present only in PEII-containing marine Synechococcus, except low-PUB (pigment type 3a) strains (Six et al., 2007; Mahmoud et al., 2017; Grébert et al. 2022). 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 but the site of this probable lyase-isomerase specificity remains to be established.
