| case <OC:Cyanobacteriota> | |
| FUNCTION | A factor required for optimal assembly of photosystem II (PSII), acting in the early stages of PSII assembly. Also plays a role in replacement of photodamaged D1 (psbA). Assists YidC in synthesis of chlorophyll-binding proteins. |
| end case | |
| case <OC:Gloeobacter> | |
| SUBUNIT | Part of early PSII assembly complexes which includes D1 (psbA) and PsbI; not found in mature PSII. Binds to the periplasmic side of PSII complexes. Interacts with YidC. |
| SUBCELLULAR LOCATION | Cell inner membrane; Lipid-anchor; Periplasmic side. Note=Associated with a PSII precusor complex on the periplasmic side of the cell inner membrane. |
| else case <OC:Cyanobacteriota> and <Feature:PS51257> | |
| SUBUNIT | Part of early PSII assembly complexes which includes D1 (psbA) and PsbI; not found in mature PSII. Binds to the lumenal side of PSII complexes. Interacts with YidC. |
| SUBCELLULAR LOCATION | Cellular thylakoid membrane; Lipid-anchor; Lumenal side. Note=Associated with a PSII precusor complex on the lumenal side of the thylakoid membrane. |
| else | |
| SUBCELLULAR LOCATION | Cellular thylakoid lumen. Note=Associated with a PSII precusor complex on the lumenal side of the thylakoid membrane. |
| end case | |
| case <OG:Chloroplast> | |
| FUNCTION | Essential for photosystem II (PSII) biogenesis; required for assembly of an early intermediate in PSII assembly that includes D2 (psbD) and cytochrome b559. |
| SUBCELLULAR LOCATION | Plastid, chloroplast thylakoid lumen. |
| end case | |
| DOMAIN | A 7-bladed beta-propeller torus, about 55 by 55 Angstroms, with a depth of about 25 Angstroms and a central pore. |
| SIMILARITY | Belongs to the Ycf48 family. |
