Inhibition of serine proteases by benzoxazinones: effects of electron withdrawal and 5-substitution.

abstract：:G-G base-paired hairpin DNA structures on template strands offer potential "road-blocks" to a traversing polymerase. Klenow polymerase (exo+) pauses while replicating through G-G base-paired hairpin DNA due to the generation of G-G:C triplex. However, exonuclease-deficient Klenow traverses through de novo generated G-...
