Abstract

Extracts of contain aminoglycoside acetyltransferase activity not previously encountered among actinomycetes. Neomycin and its derivatives (excluding butirosin) are good substrates as is the novel aminoglycoside apramycin, whereas the gentamicins and kanamycins are utilized poorly if at all. Sisomicin, which is produced by , is not acetylated. When neomycin was modified by extracts of the product, most probably 3--acetylneomycin, was inactive against cell-free protein synthesis.
