Recombinant Human MMP12 Protein, F171D Mutant, 106-263

• Cat.No.: MMP12-33H
• Product Overview: Recombinant matrix metalloproteinase-12 (MMP-12, metalloelastase, macrophage elastase) cloned from human cDNA, expressed in E. coli. The enzyme consists of the catalytic domain of human MMP-12 (residues 106-263, UniProtKB accession P39900) with the mutation F171D. The protein has been mutated to increase its stability, as the mutation drastically reduces the enzyme's rate of autoproteolysis. The catalytic activity rates are not affected by the mutation.

Specification

• Species: Human
• Source: E.coli
• Tag: Non
• Protein Length: 106-263
• Description: This gene encodes a member of the peptidase M10 family of matrix metalloproteinases (MMPs). Proteins in this family are involved in the breakdown of extracellular matrix in normal physiological processes, such as embryonic development, reproduction, and tissue remodeling, as well as in disease processes, such as arthritis and metastasis. The encoded preproprotein is proteolytically processed to generate the mature protease. This protease degrades soluble and insoluble elastin. This gene may play a role in aneurysm formation and mutations in this gene are associated with lung function and chronic obstructive pulmonary disease (COPD). This gene is part of a cluster of MMP genes on chromosome 11.
• Bio-activity: > 40 U/μg. Activity described as U=100 pmol/min at 25 centigrade using a colorimetric assay with thiopeptide Ac-Pro-Leu-Gly-[2-mercapto-4-methyl-pentanoyl]-Leu-Gly-OC2H5 (Biomol) as substrate.
