Function, purification, and crystallization of HCAR. A, interconversion of chlorophyll a and chlorophyll b with HMChl as intermediate. CAO, chlorophyll a oxygenase; CBR, chlorophyll b reductase. B, SEC profiles on a HiLoad 16/60 Superdex 200 column. The protein and its cofactors are monitored by absorbance at 280, 385, and 450 nm. C, calibration curve of logarithm of molecular mass as a function of elution volume. The HCAR elusion peak indicates an oligomeric state. D, the dark brown crystals of HCAR. The scale bar corresponds to 200 μm.
