PCC7421 strain

[fasta] [gff] [only sure] [only unsure]

Lineage

Prokarya

Cyanobacteria

Chroococcales

Gloeobacter

violaceus

Strain information

Phycobiliprotein types: PC+PEI

Pigment type: 2

Habitat: Rock

Remark: The chromophorylation of the PE of this strain is controversial. Indeed Bryant et al. (1981) reported that the alpha subunit would bind 3 PEB and the beta subunit 3 PEB and one PUB, whereas CpeA and CpeB sequences have no additional binding sites as other PEs. No obvious candidate for a lyase-isomerase was found in this genome.
