Produced in E. coli. Active recombinant matrix metalloproteinase-20 (MMP-20, enamelysin) cloned from human cDNA. The enzyme consists of residues Tyr108-Phe276 (NM_004771), which comprises the catalytic domain of human MMP-20, with a C-terminal purification tag. This represents a naturally-occurring active form of MMP-20 which lacks the C-terminal hemopexin domain.

MMP-20 functions in tooth development and is implicated in cancer and oral pathology.
