Function

function

Required for the biogenesis and accumulation of native cytochrome b6 in the thylakoid membrane. Controls the conversion of apocytochrome b6 to holocytochrome b6. Required for covalent binding of the c-type heme to cytochrome b6.

Phenotypes & Variants

Disruption phenotype

High chlorophyll fluorescence phenotype due to an impaired photosynthetic electron flow (PubMed:17971335).
Seedling lethal when grown on soil. On agar plates supplied with sucrose, seedlings grow very slowly with a chlorotic phenotype. Deficiency in the accumulation of the subunits of the cytochrome b6f complex and lack of covalent heme binding to cytochrome b6 (PubMed:17971335, PubMed:18593701).
