title: A tobacco soluble protoporphyrinogen-oxidizing enzyme similar to plant peroxidases in their amino acid sequences and immunochemical reactivity.
abstract: Partial amino acid sequences of a soluble protoporphyrinogen-oxidizing enzyme (PPO) purified from tobacco cultured cells were identified. The sequences of two regions of the soluble PPO corresponded to the acid/base catalysis and heme binding regions of plant peroxidases. Anti-soluble PPO IgG cross-reacted with these plant peroxidases. Thus, the soluble PPO seems to be a kind of peroxidase.
