Product Description
Serum copper transport and iron-oxidizing protein. Expressed in plasma at concentrations of 1-5µM. Contains six copper centers and is known to oxidize amines in a process coupled to the reduction of molecular oxygen. Has ferroxidase activity that is responsible for the oxidation of ferrous iron to its ferric form, which is necessary for efficient iron efflux from the cell (e.g. during hypoxia). Has previously been considered a target for nitric oxide (NO) and an inhibitor of endothelial nitric oxide synthase (eNOS/NOS III). Catalyzes S-nitrosothiol formation in cell culture media. Is a NO oxidase and nitrite synthase that determines endocrine NO homeostasis.

General Information
MMP-1, the classical matrix metalloproteinase, is expressed by a large number of cell types. As an example, in basal keratinocytes migrating across the dermal matrix the enzyme is invariably expressed and cleaves fibrilliar collagen type I. It was shown that the interaction of the α2β1 integrin with dermal collagen mediates induction of MMP-1 in keratinocytes at the onset of healing and that the activity of MMP-1 is needed to initiate cell movement. The cleavage of dermal collagen provides keratinocytes with a mechanism to maintain their directionality during reepithelialization (Pilcher et al. 1997).
The MMP-1 zymogens of ~56/52kDa can be activated by a stepwise mechanism through which sequential processing events occur in the propeptide region. Both proenzymes can be activated by limited digestion with trypsin or by treatment with APMA generating their respective active enzyme forms of ~46/42kDa (Wilhelm et al. 1986).
BACKGROUND/TECHNICAL INFORMATION Activity:
We recommend to dilute this enzyme preparation at least 1:10 and to take 5µl or less for the determination of activity. Specific activity can be assayed with the synthetic substrate N-(2,4)-dinitrophenyl-Pro-Gln-Gly-Ile-Ala-Gly-Gln-D-Arg (Dnp-peptide) (Masui et al.). Substrate concentration should be 0.5mg/ml in buffer 50mM TRIS-HCl, pH 7.0, 200mM NaCl, 5mM CaCl2, 1µM ZnCl2, 0.05% BRIJ35, 0.05% sodium azide, containing 0.05mg/ml albumin. One unit MMP catalyzes the hydrolysis of 1µmol Dnp-peptide/min at 37°C and pH 7.0.
We recommend to employ the fluorogenic substrate (7-Methoxycoumarin-4-yl)acetyl-Pro-Leu-Gly-Leu-N-β-Dnp-L-α,β-diaminopropionyl-Ala-Arg-NH2) (Knight et al. 1992). The hydrolysis of the Gly-Leu bond separates the highly fluorescent (7-Methoxycoumarin-4-yl)acetyl group from the 2,4-dinitrophenyl resulting in an increase of fluorogenic intensity. The substrate should be kept as a 9.15mM stock solution in DMSO (10mg/ml). In the assay the substrate concentration should be ~25mM. The assay can be performed in a 96-well microtiter plate (200µl per well) suitable for fluorogenic measurements (excitation wavelength of 328nm; emission wavelength of 393nm).

Activation:
Do not dilute enzyme for activation! Activation is required by trypsin (2µl trypsin; 1mg/ml) for 10-20 min. at 37°C and stopped by the addition of 10µl trypsin-inhibitor (2mg/ml) or aprotinin or TLCK. Activation can also be done by 2mM (final concentration) APMA for 60 min. at 37°C.

Inhibitors:
Only  the activated and not the latent forms of wild-type MMP-1 protein is able to form a complex with TIMP-1. Quite in contrast to MMP-2 (gelatinase A) and MMP-9 (gelatinase B), in MMP-1 the C-terminal hemopexin domain does not interact with TIMP-1. The integrity of the catalytic domain of MMP-1 and its ability to bind Zn2+ is absolutely required for complex formation with TIMP-1, which further underlines the importance of this region for proper regulation of enzymatic activity of MMP-1 (Vallon et al. 1997). Therefore, the enzyme is also inhibited by chelators of divalent cations like EDTA or o-phenantroline.

Hydrolysis of the Gly-Leu bond separates the highly fluorescent (7-Methoxycoumarin-4-yl)acetyl group from the 2,4-dinitrophenyl resulting in an increase of fluorogenic intensity. The Km value for the gelatinase A is 7.0x105M-1s-1. Substrate should be kept as a  9.15mM stock solution in DMSO (10mg/ml). In the assay the substrate concentration should be ~25µM. The assay can be performed in a 96-well microtiter plate (100/200µl per well) suitable for fluorogenic measurements (Ex 328 nm; Em 393 nm).

Activation:
Requires activation by 2mM (final concentration) AMPA or 1mM mersalic acid for 60-120 min. at 37°C. We do not recommend to use trypsin for activation! Do not dilute enzyme for activation!

Inhibitors:
Activated enzyme is inhibited by tissue inhibitors of matrix metalloproteinase-2 (TIMP-2) and by chelators of divalent cations like EDTA or o-phenanthroline.
