dna polymerase beta requires higher primer concentration ( km = 11.1 microm with respect to 3'-oh of the primer ) than dna polymerase gamma ( km = 0.04 microm ) or oncornaviral dna polymerase ( km = 0.08 microm ) and the enzyme represented the maximum activity in the base ratio of 2:1 with ( dt ) 12-18 and ( ra ) n suggesting the difference in reaction mechanisms of these enzymes .
