Variant remarks A13T mutation, located near the phosphorylation site (Ser-15) of the human cardiac regulatory light chain, had 3-fold lower KCa than wild-type light chain, whereas phosphorylation of this mutant increased the Ca2+ affinity 6-fold. Phosphorylated A13T demonstrated a 15-fold greater affinity for Ca2+ than phosphorylated HCRLC-WT, whereas nonphosphorylated A13T bound Ca2+ with a 3-fold

lower affinity than nonphosphorylated-WT. The binding of Ca2+ to the A13T mutant, which had the highesalpha-helical content among all FHC mutants in the apo-state, caused a decrease (not increase) in it's alpha-helical content from 29% to 25%.
