Affinity of S100A1 protein for calcium increases dramatically upon glutathionylation.

The FEBS journal - 1 May 2005

Abstract excerpt

S100A1 is a typical representative of a group of EF-hand calcium-binding proteins known as the S100 family. The protein is composed of two alpha subunits, each containing two calcium-binding loops (N and C). At physiological pH (7.2) and NaCl concentration (100 mm), we determined the microscopic binding constants of calcium to S100A1 by analysing the Ca(2+)-titration curves of Trp90 fluorescence for both the...
