... functional domains and motifs, including a PB1domain in the N-terminus, a pseudosubstrate (PS)sequence, a C1 domain of a single Cys-rich zinc-fingermotif, and a kinase domain in the C-terminus. The catalytic ... [19]. In this study we used IR spectroscopy to study the secondary structure of the catalytic domain of PKCf and the effect of its substrate, MgATP, and also to study the effect of thermal unfolding ... 32.Derivation gave the number and position, as well as an esti-mation of the bandwidth and the intensity of the bandsmaking up the amide I or I¢ region. Thereafter, curve fittingwas performed and the heights,...
