CC   -!- FUNCTION: May be a component of the oxygen-evolving complex.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane.
CC       Note=Associated with the photosystem II complex.
CC   -!- PTM: The maturation of the PSII-T precursor to its final form occurs
CC       through a two step process. First, a stromal intermediate is formed,
CC       which, upon translocation into the thylakoid membrane, is processed to
CC       the mature protein.
