- Abstract
Besides the monomeric mammalian 95 kDa progelatinase, two additional forms, a disulfide-bridged 220 kDa dimer and a 125 kDa form were isolated from human PMN leukocytes. The 125 kDa progelatinase was identified as a covalently linked, disulfide-bridged heterodimer formed of the monomer with a 25 kDa protein. This 25 kDa protein was isolated from gelatinase bound to the affinity support of gelatin-Sepharose and eluted by DTE-containing buffer. The amino acid sequence of tryptic peptides of this protein revealed homology with an alpha 2-microglobulin-related protein from rats, a protein so far unknown in humans.
