General Information | Comment | Organism |
---|---|---|
metabolism | Neo-6 is the enzyme catalysing the transamination of 2-deoxy-scyllo-inosose, DOI, using L-glutamine as an amino donor to produce 2-deoxyscyllo-inosamine as required for 2-deoxystreptamine biosynthesis. Neo-6 also catalyses the amino transfer from L-glutamine to 3-amino-2,3-dideoxy-scyllo-inosose to produce 2-deoxystrepamine, EC 2.6.1.101, the aglycon in neomycins, overview | Streptomyces fradiae |
additional information | gene neo6 of the neo gene cluster and btrR from the btr gene cluster are equivalent, genetic organization, overview | Streptomyces fradiae |
physiological function | the enzyme produces 2-deoxystreptamine (DOS), EC 2.6.1.101, which is the aglycone in neomycins, overview. Neo-6 is also the enzyme catalysing the transamination of 2-deoxy-scyllo-inosose, DOI, using L-glutamine as an amino donor to produce 2-deoxyscyllo-inosamine as required for 2-deoxystreptamine biosynthesis | Streptomyces fradiae |
