pheophorbide a + H2O constitutively expressed Chenopodium album pyropheophorbide a + methanol + CO2 overall reaction ?
pheophorbide a + H2O the enzyme catalyzes the conversion of pheophorbide a to a precursor of pyropheophorbide a (C-132-carboxyl-pyropheophorbide a). The precursor is then decarboxylated non-enzymatically to yield pyropheophorbide Chenopodium album pyropheophorbide a + methanol + CO2 overall reaction ?
