CC -!- FUNCTION: Bassianolide nonribosomal synthetase that mediates the
CC biosynthesis of bassianolide (BSL), a non-ribosomal cyclodepsipeptide
CC that shows insecticidal and cancer cell antiproliferative activity
CC (PubMed:19285149, PubMed:23608474, PubMed:23727842, PubMed:29163920,
CC PubMed:31471217, PubMed:31388353). BSLS first catalyzes the iterative
CC synthesis of an enzyme-bound dipeptidol monomer intermediate from D-2-
CC hydroxyisovalerate and L-leucine before performing the condensation and
CC cyclization of 4 dipeptidol monomers to yield the cyclic tetrameric
CC ester bassianolide (PubMed:23608474, PubMed:23727842, PubMed:29163920,
CC PubMed:31471217, PubMed:31388353). The N-methyltransferase MT domain is
CC responsible for the methylation of the leucine residues of bassianolide
CC (PubMed:29163920, PubMed:31388353). BSLS is flexible with both the
CC amino acid and hydroxyl acid precursors, and produces bassianolide as
CC the major product (containing N-methyl-L-Leu), together with small
CC amounts of beauvericin and its analogs beauvericins A-C (containing N-
CC methyl-L-Phe) (PubMed:31388353). {ECO:0000269|PubMed:19285149,

CC Vmax=0.05 uM/min/mg enzyme toward L-leucyl-N-acetyl-cysteamine

CC -!- INDUCTION: Expression is induced during insect infection.
CC {ECO:0000269|PubMed:25912088}.
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 additional domains required for further modifications are also present
CC (Probable). Bassianolide synthetase has the C1-A1-T1-C2-A2-MT-T2a-T2b-
CC C3 domain organization. During catalysis, C3 and C2 take turns to
CC incorporate the two biosynthetic precursors into the growing
CC depsipeptide chain that swings between T1 and T2a/T2b with C3 cyclizing
CC the chain when it reaches the full length (PubMed:23727842,
CC PubMed:29163920, PubMed:31471217, PubMed:31388353). The N-
CC methyltransferase MT domain in module 2 is responsible for the
CC methylation of the leucine residues integrated in the backbone
CC structure (PubMed:29163920, PubMed:31388353).
CC {ECO:0000269|PubMed:23727842, ECO:0000269|PubMed:29163920,
CC ECO:0000269|PubMed:31388353, ECO:0000269|PubMed:31471217, ECO:0000305}.
CC -!- DISRUPTION PHENOTYPE: Abolishes the production of bassianolide but does
CC not affect the biosynthesis of beauvericin (PubMed:19285149).
CC Attenuates the virulence against insects, including the corn earworm
CC (Helicoverpa zea), the fall armyworm (Spodoptera exigua) and the
CC greater wax moth (Galleria mellonella) (PubMed:19285149).
CC {ECO:0000269|PubMed:19285149}.
CC -!- BIOTECHNOLOGY: Shows insecticidal activity and contributes to the
CC virulence of the fungus against insects including the corn earworm
CC (Helicoverpa zea), the fall armyworm (Spodoptera exigua) and the
CC greater wax moth (Galleria mellonella) (PubMed:19285149). Bassianolide
CC possesses antitumor activities and displays significant cytotoxicity
CC against several human tumor cell lines, including A549, SK-OV-3, HepG2,
CC HCT-15, MCF-7 and MDA-MB 231 cell lines with IC(50) values of 7.24,
CC 8.44, 15.39, 6.40, 11.42 and 3.98 ug/ml respectively (PubMed:27676608).
CC Bassianolide especially induces G0/G1 arrest associated with a decrease
CC of cyclin A, D1 and an increase of p53, MDM2, and p21 expression in
CC human breast adenocarcinoma cell lines (PubMed:27676608).
CC {ECO:0000269|PubMed:19285149, ECO:0000269|PubMed:27676608}.
CC -!- SIMILARITY: Belongs to the NRP synthetase family. {ECO:0000305}.
