CC   -!- FUNCTION: Precursor peptide that leads to mycofactocin (MFT) after
CC       extensive post-translational modifications by enzymes encoded by
CC       adjacent genes. Mycofactocin acts as a redox cofactor of nicotinamide-
CC       dependent oxidoreductases encoded in the same locus.
CC       {ECO:0000250|UniProtKB:P0DUE9}.
CC   -!- PTM: The post-translational modifications that lead to mycofactocin
CC       involve oxidative decarboxylation of the C-terminal tyrosine residue
CC       catalyzed by MftC, introduction of a tyramine-valine cross-link,
CC       removal of the modified C-terminal dipeptide by MftE. The released
CC       dipeptide then undergoes oxidative deamination by MftD, glycosylation
CC       by MftF and methylation by an unknown enzyme.
CC       {ECO:0000250|UniProtKB:P0DUE9}.
CC   -!- MISCELLANEOUS: Mycofactocin is classified as a ribosomally synthesized
CC       and post-translationally modified peptide (RiPP). {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the mycofactocin precursor peptide family.
CC       {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=CCP43435.1; Type=Erroneous initiation; Note=Extended N-terminus.; Evidence={ECO:0000305};
