CC -!- FUNCTION: Required for the insertion of integral membrane proteins into
CC the membrane. Probably plays an essential role in the integration of
CC proteins of the respiratory chain complexes. Involved in integration of
CC membrane proteins that insert dependently and independently of the Sec
CC translocase complex (By similarity). Addition of green fluorescent
CC protein (GFP) to the C-terminus leads to photoinhibition at 80
CC umol/m(2)/s light intensity, reduced amounts of pigment, altered energy
CC transfer between the antenna systems and the reaction centers of PSI
CC and PSII, and impaired integration of PSII reaction center protein D1
CC (psbA) into membranes, suggesting it probably also aids protein
CC insertion, folding and/or assembly of membrane complexes destined for
CC the thylakoid (PubMed:15498761, PubMed:16905652).
CC {ECO:0000250|UniProtKB:P25714, ECO:0000269|PubMed:15498761,
CC ECO:0000269|PubMed:16905652}.
CC -!- SUBUNIT: Specifically interacts with transmembrane segments of nascent
CC integral membrane proteins during membrane integration (By similarity).
CC Interacts with the precursor of PSII reaction center D1
CC (PubMed:16905652). Coimmunoprecipitates with CyanoP (tlr2075), FtsH2,
CC FtsH3, Phb1 (slr1106), Ycf39 and Ycf48 (PubMed:30061392).
CC {ECO:0000250|UniProtKB:P25714, ECO:0000269|PubMed:16905652,
CC ECO:0000269|PubMed:30061392}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000269|PubMed:16905652,
CC ECO:0000269|PubMed:18600052}; Multi-pass membrane protein
CC {ECO:0000269|PubMed:16905652, ECO:0000269|PubMed:18600052}.
CC -!- DISRUPTION PHENOTYPE: Merodiplod cells have greatly altered thylakoid
CC morphology, and about 40% photosynthetic pigements, photosynthetic
CC electron transport and oxygen evolution. {ECO:0000269|PubMed:15498761}.
CC -!- SIMILARITY: Belongs to the OXA1/ALB3/YidC family. Type 1 subfamily.
CC {ECO:0000305}.
