CC   -!- FUNCTION: Nonribosomal peptide synthase required for the biosynthetis
CC       of epichloenin A, an extracellular siderophore that plays a crucial
CC       role in endophyte-grass symbioses (PubMed:23658520). SidN assembles
CC       epichloenin A by activating and incorporating three trans-
CC       anhydromevalonylhydroxyornithine (trans-AMHO), 1 glutamine and 4
CC       glycine moieties (PubMed:23658520). Trans-AMHO is produced from L-
CC       ornithine via 2 steps involving a L-ornithine N(5)-monooxygenase and an
CC       AHMO-N(5)-transacylase that have still to be identified
CC       (PubMed:23658520). The third adenylation domain (A3) of sidN
CC       incorporates the hydroxamate groups of the siderophore which forms an
CC       octahedral iron complex (PubMed:23658520). The other component amino
CC       acids are assembled by sidN adenylation domains A1 and A2
CC       (PubMed:23658520). {ECO:0000269|PubMed:23658520}.
CC   -!- PATHWAY: Siderophore biosynthesis. {ECO:0000269|PubMed:23658520}.
CC   -!- INDUCTION: Expression is repressed by iron (PubMed:23658520).
CC       {ECO:0000269|PubMed:23658520}.
CC   -!- DOMAIN: NRP synthetases are composed of discrete domains (adenylation
CC       (A), thiolation (T) or peptidyl carrier protein (PCP) and condensation
CC       (C) domains) which when grouped together are referred to as a single
CC       module (By similarity). Each module is responsible for the recognition
CC       (via the A domain) and incorporation of a single amino acid into the
CC       growing peptide product (By similarity). Thus, an NRP synthetase is
CC       generally composed of one or more modules and can terminate in a
CC       thioesterase domain (TE) that releases the newly synthesized peptide
CC       from the enzyme (By similarity). Occasionally, methyltransferase
CC       domains (responsible for amino acid methylation) are present within the
CC       NRP synthetase (By similarity). SdiN has the following architecture: A-
CC       T-C-A-T-C-A-T-C-T-C-T-C (PubMed:23658520).
CC       {ECO:0000250|UniProtKB:A0A144KPJ6, ECO:0000305|PubMed:23658520}.
CC   -!- DISRUPTION PHENOTYPE: Leads to the accumulation of the intermediate N-
CC       5-trans-anhydromevalonyl-N-5-hydroxyornithine (trans-AMHO), displays
CC       sensitivity to oxidative stress and shows deficiencies in both
CC       polarized hyphal growth and sporulation (PubMed:23658520). Changes its
CC       interaction with the plant Lolium perenne from mutually beneficial to
CC       antagonistic (PubMed:23658520). {ECO:0000269|PubMed:23658520}.
CC   -!- SIMILARITY: Belongs to the NRP synthetase family. {ECO:0000305}.
