A tentative elucidation of the sequence of human triosephosphate isomerase by homology peptide mapping

Abstract

By utilizing homologous peptide mapping and amino acid analysis of recovered peptides, it has been possible to infer much of the sequence of human triosephosphate isomerase. This has been achieved with less than 5 mg of the human enzyme. The enzyme shows a great sequence homology with the rabbit enzyme. The methods used in this study can provide a rapid procedure for gaining structural information on human enzymes available only in microgram or milligram quantities.
