Abstract

<jats:title>Abstract</jats:title> <jats:p>The DFT computational geometry and CO stretching frequency of the active center of iron sulfur cluster free hydrogenase (Hmd) indicate that the active site contains low-spin Fe(II) center coordinated with two COs, cysteine, either acylpyridone and water or acylpyridinol and hydroxide.</jats:p>
