Structural changes of the sarcoplasmic reticulum Ca(2+)-ATPase upon nucleotide binding studied by fourier transform infrared spectroscopy

Changes in the vibrational spectrum of the sarcoplasmic reticulum Ca(2+)-ATPase upon nucleotide binding were recorded in H(2)O and (2)H(2)O at -7 degrees C and pH 7.0. The reaction cycle was triggered by the photochemical release of nucleotides (ATP, ADP, and AMP-PNP) from a biologically inactive pr...
