Patent ID: 7229796

Claim:
A recombinant host cell, wherein the recombinant host cell is a Bacillus cell comprising a recombinant vector comprising a purified nucleic acid segment having a coding region encoding enzymatically active hyaluronan synthase, wherein the coding region is under control of a promoter, and wherein the coding region encoding enzymatically active hyaluronan synthase is selected from the group consisting of: (a) a coding region encoding enzymatically active hyaluronan synthase of SEQ ID NO:16; (b) a coding region encoding enzymatically active hyaluronan synthase of SEQ ID NO:8; (c) a nucleotide sequence in accordance with SEQ ID NO:15; (d) a nucleotide sequence in accordance with SEQ ID NO:7; (e) a coding region encoding enzymatically active hyaluronan synthase that is at least 70% identical to SEQ ID NO:14; and (f) a coding region encoding enzymatically active hyaluronan synthase, wherein the coding region is capable of hybridizing to a complementary sequence of SEQ ID NO:13.
