Testosteronan, a heparosan analog having the structure [-4-D-GlcUA-α1,4-D-GlcNAc-α1-] n , is produced by testosteronan synthase, a single protein that is a dual-action catalyst that utilizes UDP-GlcUA and UDP-GlcNAc to synthesize a polysaccharide having the structure [-4-D-GlcUA-α1,4-D-GlcNAc-α1-] n . |
