Figure 1.
UV/VIS spectra of H60C_NP1 (11 mM, in phosphate buffered saline, pH 7.4) in complex with selected imidazole ligands. NP1 (11 mM, phosphate buffered saline, pH 7.4) is shown for comparison. The Soret maxima are: H60C: 389 nm; H60C/Imd: 411 nm; H60C/Hsm: 405 nm; H60C/nBuIm: 424 nm; NP1: 405 nm.
