摘要
<jats:p>The gene coding for cyclohexanone monooxygenase from Acinetobacter sp. strain NCIB 9871 was isolated by immunological screening methods. We located and determined the nucleotide sequence of the gene. The structural gene is 1,626 nucleotides long and codes for a polypeptide of 542 amino acids; 389 nucleotides 5' and 108 nucleotides 3' of the coding region are also reported. The complete amino acid sequence of the enzyme was derived by translation of the nucleotide sequence. From a comparison of the amino acid sequence with consensus sequences of nucleotide-binding folds, we identified a potential flavin-binding site at the NH2 terminus of the enzyme (residues 6 to 18) and a potential nicotinamide-binding site extending from residue 176 to residue 208 of the protein. An overproduction system for the gene to facilitate genetic manipulations was also constructed by using the tac promoter vector pKK223-3 in Escherichia coli.</jats:p>
