Equilibrium constants for the binding of protoporphyrin to serum albumin and hemopexin and liver cytosolic fatty acid-binding protein of the rat were determined fluorometrically. The experimental equilibrium constant [10(6) M-1 (mean +/- S.D.)] values were 8.4 +/- 1.3, 10.0 +/- 2.4 and 34.0 +/- 3.0
Binding affinity and binding-pocket polarity is determined for intracellular fatty acid-binding protein (FABP) from aerobic muscle of Chaenocephalus aceratus, the Antarctic icefish, and from rat heart. FABPs bind fatty acids via weak-bond forces (both ionic and hydrophobic), and these bond forces ar
