X-band EPR spectra of Fe(III) A) WT hCBS and B) R266K hCBS. Proteins (141 µM WT and 235 µM R266K) were in 100 mM CHES buffer and 100 mM NaCl, pH 8.6. Each spectrum represents an average of 10 scans taken at 10K, with 9.379 GHz microwave frequency, 8.000 G modulation amplitude, 100 kHz modulation frequency, 74 dB receiver gain, 163.84 ms time constant and a power of 1.002 mW.
