title: Complete nucleotide sequences and comparison of the structural genes of two 2-haloalkanoic acid dehalogenases from Pseudomonas sp. strain CBS3.
abstract: The nucleotide sequences of two DNA segments from Pseudomonas sp. strain CBS3 that code for two different haloalkanoic acid halidohydrolases were determined. Two open reading frames with coding capacities of 227 amino acids (corresponding to a molecular mass of 25,401 Da) and 229 amino acids (corresponding to a molecular mass of 25,683 Da) were identified as structural genes of 2-haloalkanoic acid dehalogenases I (dehCI) and II (dehCII) by comparison with the N-terminal amino acid sequences of these enzymes. Comparison of the two sequences revealed 45% homology on the DNA level and 37.5% homology on the amino acid level. No homology with other known protein or nucleotide sequences was found.
