ENZYME 3D STRUCTURE
dilution of purified enzyme with a glycine buffer, pH 8.5, containing 1.0 mM DTT, and 0.04% w/v polyvinyl alcohol 50000, produces a striking and significant increase in enzyme activity when diluted 1:2 to 1:10
-
10 kDa: increases the enzyme activity by 36% at 0.02% w/v, 50 kDa: increases the enzyme activity by 21% at 0.02% w/v
-
required for optimal activity of DNA ligase I but not for DNA ligase II activity
