title: A 20-kDa protein with the GTP-binding and trypsin inhibitory activities from Glycine max.
abstract: A 20-kDa protein (p20) with a GTP binding activity was purified from the cultured cells of Glycine max (soybean). The amino acid sequence of p20 showed 65% identity in a 23 amino acid overlap against the Kunitz-type trypsin inhibitor of soybean reported. Furthermore, it was found that a Kunitz-type soybean trypsin inhibitor of commercial origin also binds GTP.
