S146A MUTANT OF THERMOMYCES (HUMICOLA) LANUGINOSA LIPASE COMPLEX WITH OLEIC ACID
Overview
The binding of Thermomyces lanuginosa lipase and its mutants [TLL(S146A), TLL(W89L), TLL(W117F, W221H, W260H)] to the mixed micelles of, cis-parinaric acid/sodium taurodeoxycholate at pH 5.0 led to the quenching, of the intrinsic tryptophan fluorescence emission (300-380 nm) and to a, simultaneous increase in the cis-parinaric acid fluorescence emission, (380-500 nm). These findings were used to characterize the Thermomyces, lanuginosa lipase/cis-parinaric acid interactions occurring in the, presence of sodium taurodeoxycholate.The fluorescence resonance energy, transfer and Stern-Volmer quenching constant values obtained were, correlated with the accessibility of the tryptophan residues to the, cis-parinaric acid and with the lid opening ability of Thermomyces, lanuginosa lipase (and its ...
