CC   -!- FUNCTION: Nonribosomal peptide synthetase; part of the gene cluster
CC       that mediates the biosynthesis of penicillin, the world's most
CC       important antibiotic (PubMed:1368505, PubMed:9266851, PubMed:21889568).
CC       The first step of the pathway is performed by the trimodular NRPS acvA
CC       that produces the tripeptide N-[(5S)-5-amino-5-carboxypentanoyl]-L-
CC       cysteinyl-D-valine (LLD-ACV or ACV) via condensation of the 3 residues
CC       L-2-aminoadipate, L-cysteine and L-valine (PubMed:9266851,
CC       PubMed:9355751, PubMed:19686863, PubMed:21889568). The precursor amino
CC       acids for penicillin biosynthesis are withdrawn from the vacuolar amino
CC       acid pool by the MFS-type transporter penV (PubMed:8416970,
CC       PubMed:22777282). Each of the constituent amino acids of the tripeptide
CC       ACV are activated as aminoacyl-adenylates with peptide bonds formed
CC       through the participation of amino acid thioester intermediates
CC       (PubMed:9266851, PubMed:21889568). The tripeptide ACV is then cyclized
CC       to form isopenicillin N (IPN) by the isopenicillin N synthase ipnA that
CC       forms the beta-lactam nucleus (PubMed:1368505, PubMed:1369045,
CC       PubMed:1588566). Finally, the alpha-aminoadipyl side chain is exchanged
CC       for phenylacetic acid by the isopenicillin N acyltransferase aatA to
CC       yield penicillin (PubMed:2120195, PubMed:2110531, PubMed:1368505). This
CC       step occurs in the peroxisomal matrix and the penM and paaT
CC       transporters are involved in the isopenicillin N and phenylacetic acid
CC       import into the peroxisome, respectively (PubMed:23053082).

CC   -!- INDUCTION: Expression is repressed by glucose (PubMed:3096965). The
CC       transcription factor rfx1 controls penicillin biosynthesis through the
CC       regulation of the acvA, ipnA and aatA transcription (PubMed:22960281).
CC       The promoter heptameric sequence 5'-TTAGTAA-3' is the binding site for
CC       the transcriptional activator named penicillin transcriptional
CC       activator 1 (PTA1) (PubMed:10644695). Multiple additional DNA-binding
CC       proteins appear to bind to the promoter, including the nuclear factor A
CC       (NF-A) that recognizes an the 5'-GCCAAGCC-3' sequence or the global-
CC       acting nitrogen regulatory protein NIT2 that binds strongly at a single
CC       site that contains two closely spaced GATA sequences (PubMed:7614558).

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. Each module is responsible for the recognition (via the A
CC       domain) and incorporation of a single amino acid into the growing
CC       peptide product. Thus, an NRP synthetase is generally composed of one
CC       or more modules and can terminate in a thioesterase domain (TE) that
CC       releases the newly synthesized peptide from the enzyme. Occasionally,
CC       epimerase (E) domains (responsible for L- to D-amino acid conversion)
CC       are present within the NRP synthetase. GliP has the following
CC       architecture: A-T-C-A-T-C-A-T-E-TE. {ECO:0000269|PubMed:21889568,
CC       ECO:0000269|PubMed:9266851}.
CC   -!- SIMILARITY: Belongs to the NRP synthetase family. {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
