Heparan sulfate (HS) polysaccharide chains have been shown to orchestrate distinct biological functions in several systems. Study of HS structure-function relations is, however, hampered due to the lack of availability of HS in suffi cient quantities as well as the molecular heterogeneity of naturally occurring HS. Enzymatic synthesis of HS is an attractive alternative to the use of naturally occurring HS, as it reduces molecular heterogeneity, or a long and daunting chemical synthesis of HS. Heparosan, produced by E. coli K5 bacteria, has a structure similar to the unmodifi ed HS backbone structure and can be used as a precursor in the enzymatic synthesis of HS-like polysaccharides. Here, we describe an enzymatic approach to synthesize several specifi cally sulfated HS polysaccharides for biological studies using the heparosan backbone and a combination of recombinant biosynthetic enzymes such as C5-epimerase and sulfotransferases.
