RT lividomycin, paromomycin and butirosin.";
RL Submitted (JUN-2004) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Catalyzes the PLP-dependent transamination of 2-deoxy-scyllo-
CC inosose (2-DOI) to form 2-deoxy-scyllo-inosamine (2-DOIA) using L-
CC glutamine as the amino donor. Also catalyzes the transamination of 3-
CC amino-2,3-dideoxy-scyllo-inosose (keto-2-DOIA) into 2-deoxystreptamine
CC (2-DOS). {ECO:0000250|UniProtKB:Q6L739}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2-deoxy-L-scyllo-inosose + L-glutamine = 2-deoxy-scyllo-
CC inosamine + 2-oxoglutaramate; Xref=Rhea:RHEA:34147,
CC ChEBI:CHEBI:16769, ChEBI:CHEBI:58359, ChEBI:CHEBI:64796,
CC ChEBI:CHEBI:65003; EC=2.6.1.100;
CC Evidence={ECO:0000250|UniProtKB:Q6L739};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=3-amino-2,3-dideoxy-scyllo-inosose + L-glutamine = 2-
CC deoxystreptamine + 2-oxoglutaramate; Xref=Rhea:RHEA:34151,
CC ChEBI:CHEBI:16769, ChEBI:CHEBI:58359, ChEBI:CHEBI:65002,
CC ChEBI:CHEBI:65069; EC=2.6.1.101;
CC Evidence={ECO:0000250|UniProtKB:Q6L739};
CC -!- COFACTOR:
CC Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC Evidence={ECO:0000250};
CC -!- PATHWAY: Metabolic intermediate biosynthesis; 2-deoxystreptamine
CC biosynthesis; 2-deoxystreptamine from D-glucose 6-phosphate: step 2/4.
CC -!- PATHWAY: Antibiotic biosynthesis; lividomycin biosynthesis.
CC -!- SIMILARITY: Belongs to the DegT/DnrJ/EryC1 family. L-glutamine:2-deoxy-
CC scyllo-inosose/scyllo-inosose aminotransferase subfamily.
CC {ECO:0000305}.
