23 For YEpTAPL(K546M)His, the DraIII-NgoMI fragment from phTAPL(K545M) plasmid, which has a mutation of Lys (AAG) at position 546 to Met (AtG) by PCR technique reported by Imai et al. [11] using mutated primers, was excised and replaced by the DraIII-NgoMI fragment of YEpTAPLHis. Login to comment
83 For this purpose, we constructed an expression plasmid for hTAPL(K545M) harboring mutation in the Walker A motif, and it was introduced into yeast. Login to comment
84 Prior to drug sensitivity assay, we determined the ATP-binding capabilities of hTAPL and hTAPL(K545M). Login to comment
85 Expression of hTAPL(K545M) was similar in amounts compared with that of hTAPL by means of Western blotting. Login to comment
