In the present paper we first show that PGGHG is the product of ATHL1 gene as follows. (1) PGGHG was purified from chick embryos and digested with trypsin. LC-MS/MS analysis suggested the tryptic-peptides were from the ATHL1 gene product. (2) Chick embryo ATHL1 cDNA was cloned to a cloning and expression vector and two plasmid clones with different ATHL1 CDS insert were obtained. (3) Each plasmid DNA was transformed into Escherichia coli cells for expression and two isoforms of chicken PGGHG were obtained. (4) Both isoforms effectively released glucose from type IV collagen. Next, we searched for carboxyl residues crucial for catalytic activity as follows; human ATHL1 cDNA was cloned into a cloning and expression vector and 18 mutants were obtained by site-directed mutagenesis for 15 carboxyl residues conserved in ATHL1 of jawed vertebrates. The expression analysis indicated that substitutions of Asp301, Glu430 and Glu574 with sterically conservative (D301N, E430Q, E574Q) or functionally conservative (D301E, E430D, E574D) residues led to the complete elimination of enzyme activity. These findings lead us to the conclusion that PGGHG is encoded by ATHL1 and three carboxyl residues (corresponding to Asp301, Glu430 and Glu574 of human PGGHG) might be involved in the catalytic site of PGGHG."xsd:string |
