title: [Molecular cloning and amino acid composition analysis of a halophilic thiolase gene].
abstract: 5' and 3' end sequence of acaBl gene as primers, the gene of halophilic thiolase from haloarchae, Halobacterium sp. ZP-6 was cloned and its amino acid composition was calculated. Compared with non-halophilic thiolase, the halophilic thiolase contains more negative charge amino acid, less positive amino acid and less strong hydrophobic amino acid, and use preferably small side-chain amino acid. Those suggest that electrostatic screen, hydrophobic effect and surface tension all contribute to halophilic properties of thiolase.
