A mixture of antiviral nucleoside antibiotics produced by Streptomyces lysosuperificus. It contains at least 10 homologues comprising uracil, N-acetylglucosamine, an 11-carbon aminodialdose called tunicamine, and a fatty acid linked to the amino group of the tunicamine. The homologues vary in the composition of the fatty acid moiety.
Note: Use of the qualifier "multiple interactions" designates that the annotated interaction
is comprised of a complex set of reactions and/or regulatory events, possibly involving
additional chemicals and/or gene products.
