Abstract A peptide ranging from residues 229 to 240 (ENESANEGYRFG) of D1 protein was synthesized by stepwise solid-phase method. Resolution enhancement techniques were combined with band curve-fitting procedures to quantitate the FTIR spectra in the amide I' region (1700-1600 cm-1). FTIR analysis showed that DCMU induced drastic structural modification with a relative decrease of the unordered structure and turns, and a substantial increase of α-helix, which indicated that a much more compact structure was formed when DCMU was applied. The results may reflect molecular information for the protective effect of DCMU against photoinhibition.
