Rat liver betaine–homocysteine S-methyltransferase equilibrium unfolding: insights into intermediate structure through tryptophan substitutions

Equilibrium folding of rat liver BHMT (betaine–homocysteine methyltransferase), a TIM (triosephosphate isomerase)-barrel tetrameric protein, has been studied using urea as denaturant. A combination of activity measurements, tryptophan fluorescence, CD and sedimentation-velocity studies suggested a m...
