Photosystem II assembly lipoprotein Ycf48

UniProtKB accession:  P73069

Grouped By:  Matching UniProtKB accession

UniProtKB description:  A factor required for optimal assembly of photosystem II (PSII) which acts in the early stages of PSII assembly. Also plays a role in replacement of photodamaged D1 (psbA) (PubMed:18550538). May interact with precursor D1 to prevent its premature processing before association with D2 (psbD) (Probable) (PubMed:18550538). May also play a role in chlorophyll insertion into chlorophyll-binding proteins (Probable) (PubMed:18550538). Increasing levels of chlorophyll precursors partially suppresses deletion of this protein, supporting the idea that Ycf48 assists YidC in synthesis of chlorophyll-binding proteins (PubMed:30061392). The Ycf39-Hlip complex binds D1 at an early stage of PSII assembly along with Ycf48, ribosomes and ChlG, the last enzyme in chlorophyll biosynthesis; it may be involved in chlorophyll reuse and delivery to D1 in the initial stages of PSII assembly (PubMed:24681620).
