Abstract
Modified alkaline phosphatases of bacterial origin (BAP or bacterial alkaline phosphatase) which consist of a bacterial alkaline phosphatase sequence in which at least one of the amino acid residues in position 329 or in position 330 is replaced by another amino acid residue, which modified bacterial alkaline phosphatases exhibit both significantly improved enzymic properties and an increased thermal stability, and their applications, in particular in immunoenzymic assays (reagents and diagnostic kits). Method for selecting mutants of alkaline phosphatases which possess significantly improved enzymic properties.
