TylF TylFQ138H, F232Y TylFT36S, V54A TylFY139F TylFL123P, N165S, V182G TylFV54D
TmB (°C) 38.358 36.74 29.609 35.071 37.549 34.616
TmB+m (°C) 41.493 38.799 37.072 36.022 37.862 39.297
TmB+m+SAM 46.774 42.903 43.118 44.978 39.642 42.419
TmB+m+SAH (°C) 46.778 44.057 41.909 41.05 45.453 45.09
ΔTmm (°C) 3.135 2.059 7.463 4.681 0.951 0.313
ΔTmSAM (°C) 5.281 4.104 6.046 5.681 3.62 4.557
ΔTmSAH (°C) 5.285 5.258 4.837 1.753 9.431 7.228

B, buffer; m, macrocin; TmB was calculated in the buffer system and so on, the average of the three duplications on show; ΔTm was calculated by the following formula: ΔTmm = TmB+m -TmB; ΔTmSAM = TmB+m+SAM - TmB+m; ΔTmSAH = TmB+m+SAH -TmB+m.
