Also known as
F12A21.13; F12A21_13; photosystem II BY; PSBY-1; PSBY-2; YCF32
Summary
PsbY precursor (psbY) mRNA. This single nuclear gene is imported into the chloroplasts where it is processed into two integral membrane proteins with identical topology (PsbY-1 and PsbY-2). The protein appears to bind manganese but its role is not well understood.
