TypeIDPosition(s)Description
ChainPRO_00001991271-162C-phycocyanin alpha subunit

Post-translational modification

Contains one covalently linked phycocyanobilin chromophore.

Interaction

Subunit

The alpha and beta subunits exhibit high affinity for one another and form heterodimers. These heterodimers form heterohexamers of 3 alpha and 3 beta subunits which, in turn, aggregate into a heterododecamer consisting of 2 heterohexamers.

Family & Domains

Sequence similarities

Belongs to the phycobiliprotein family.
