Patent ID: 8026091

Claim:
A DNA polymerase wherein the polymerase has at least 90% sequence identity to SEQ ID NO:20 or SEQ ID NO:21, comprising A-G-X 1 -X 2 -F-X 3 -X 4 -X 5 -S-X 6 -X 7 -Q-X 8 -X 9 -X 10 -X 11 -L-X 12 -X 13 -X 14 -X 15 (SEQ ID NO:33), wherein X 2 , X 5 , X 6 , X 9 , and X 10 are any amino acid, X 1 is H, E or Q, X 3 is N or H, X 4 is L or I, X 7 is D, K or T, X 8 is L or V, X 11 is V, I or L, X 12 is F or Y, X 13 is G, X 14 is K or E, and X 15 is L or Q; wherein the polymerase has an increased nucleic acid extension rate relative to a DNA polymerase that is identical with the exception that X 13 is E.
