ATOMIC RESOLUTION STRUCTURE OF MICROCOCCUS LYSODEIKTICUS CATALASE COMPLEXED WITH NADPH
Overview
The crystal structure of the bacterial catalase from Micrococcus, lysodeikticus has been refined using the gene-derived sequence both at, 0.88 A resolution using data recorded at 110 K and at 1.5 A resolution, with room-temperature data. The atomic resolution structure has been, refined with individual anisotropic atomic thermal parameters. This has, revealed the geometry of the haem and surrounding protein, including many, of the H atoms, with unprecedented accuracy and has characterized, functionally important hydrogen-bond interactions in the active site. The, positions of the H atoms are consistent with the enzymatic mechanism, previously suggested for beef liver catalase. The structure reveals that a, 25 A long channel leading to the haem is filled by partially occupied, water ... [(full description)]
