  • Title: Hexokinase A from mammalian brain: comparative peptide mapping and immunological studies with monoclonal antibodies.
    Author: Ureta T, Smith AD, Wilson JE.
    Journal: Arch Biochem Biophys; 1986 Apr; 246(1):419-27. PubMed ID: 3963828.
    Abstract:
    Immunological reactivity of partially purified hexokinase A (ATP:D-hexose 6-phosphotransferase, EC 2.7.1.1) from brain of several vertebrate species has been compared by using enzyme-linked immunosorbent assay and seven monoclonal antibodies raised against the rat brain enzyme. The epitopes recognized by three of these antibodies have been rather widely conserved among the species examined (rat, mouse, guinea pig, rabbit, cat, dog, sheep, cow, pig, chicken), while this was not the case for the epitopes recognized by the other antibodies, which differed markedly in their distribution among these species. The domain structure of these enzymes has been examined by peptide mapping (after limited tryptic digestion) in conjunction with immunoblotting techniques employing monoclonal antibodies. The results indicate that the overall domain structure of these enzymes is similar to that previously described for rat brain hexokinase A, but that there are significant differences in the size of these domains in enzymes from different species.
