Abstract:
An orange- coloured (ORP) protein from D.gigas, a sulphate reducer bacterium, has been previously shown by extended X-ray absorption fine structure to contain a novel mixed-metal sulphide cluster of the type of [S2MoS2CuS2MoS2]. We report here the purification and the biochemical/spectroscopic characterisation of this novel protein. The cluster is not covalently bound to the polypeptide chain. The gene sequence coding for ORP as well as the amino acid sequence was determined. The putative biologic function of ORP was discussed.
