CC -!- FUNCTION: Cytochrome P450 monooxygenase; part of the gene cluster that
CC mediates the biosynthesis of aspirochlorine (or antibiotic A30641), an
CC unusual halogenated spiro compound with distinctive antifungal
CC properties due to selective inhibition of protein biosynthesis, and
CC which is also active against bacteria, viruses, and murine tumor cells
CC (PubMed:25302411). The non-ribosomal peptide synthetase (NRPS) aclP is
CC responsible the formation of the diketopiperazine (DKP) core from the
CC condensation of 2 phenylalanine residues (PubMed:25302411). One Phe
CC residue is tailored into chlorotyrosine by hydroxylation and
CC chlorination, whereas the second Phe undergoes an unprecedented C-C
CC bond cleavage to be converted into glycine (PubMed:25302411). After
CC formation of the DKP, sulfur is incorporated into the DKP by
CC conjugation with glutathione by aclG, followed by its stepwise
CC degradation to the thiol by aclI, aclJ and aclK, and the dithiol
CC oxidation by aclT (PubMed:25302411). In addition, oxygenases (aclB,
CC aclC, aclL and aclO) and O-methyltransferases (aclM and aclU) act as
CC tailoring enzymes to produce the intermediate dechloroaspirochlorine
CC (PubMed:25302411). Ultimately, chlorination of dechloroaspirochlorine
CC by the halogenase aclH is the last step in the aspirochlorine pathway
CC (PubMed:25302411). {ECO:0000269|PubMed:25302411}.
