An early intermediate of refolding alpha-lactalbumin forms within 20 ms

FEBS Lett. 1987 Nov 2;223(2):327-9. doi: 10.1016/0014-5793(87)80313-7.

Abstract

The kinetics of alpha-lactalbumin refolding were studied by the stopped-flow method with the registration of CD and intrinsic fluorescence at several wavelengths. It was shown that the early kinetic intermediate forms during the dead-time of the experiment (20 ms). This intermediate has a considerable amount of secondary structure and unpolar clusters in its molecular structure but has no rigid tertiary structure.
