1. A purified polynucleotide which encodes a thermostable polypeptide comprising an amino acid sequence having at least 85% identity to residues 13-555 of SEQ ID NO: 26, wherein said polypeptide has (a) a mutation at E465, (b) a mutation at M470 wherein said mutation at M470 is not M470R, or (c) a mutation at M470 and a mutation at E465.
