    Lysine residues on proMMP-1 or TIMP-1 were alkylated (Alk MMP-1 or Alk TIMP-1) by incubation with a 50-fold molar excess of Sulfo-NHS-acetate at 4°C for 2 hours. The alkylated proteins were then dialyzed into HBS + 1 mM CaCl2. Alk or unmodified proMMP-1 was then activated and complexed with either unmodified TIMP-1 or Alk TIMP-1. The experiment was repeated 3 times. (A) Activity for each MMP-1 species or complex was determined by fluorescent substrate assay using either 20 nM of unmodified or 40 nM of alkylated species or complex. For each replicate, background hydrolysis of the substrate was subtracted and the rate determined from the slope of the linear regression of the data. (B-E) LRP1 was immobilized on a CM5 chip and 75 nM of unmodified (blue) or 100 nM alkylated (orange) MMP-1 or TIMP-1 species or complex were injected over the chip.

    (A) Schematic of the bivalent binding model used to fit the data. In this model, the MMP-1 ligand contains two regions (a-b) that interact with two LDLa ligand binding repeats on LRP1 (AB). The first region on MMP-1 (a) docks into an LDLa repeat (A) to form the initial complex. Then, the second region on MMP-1 (b) docks into the remaining LDLa repeat (B) to form the bivalent complex. (B) Increasing concentrations (4.7, 9.4, 18.7, 37.5, 75, and 150 nM) of proMMP-1 were injected over the LRP1-coated surface. (C) Increasing concentrations (4.7, 9.4, 18.7, 37.5, 75, and 150 nM) of active MMP-1 were injected over the LRP1-coated surface. (D) Increasing concentrations (2.3, 4.7, 9.4, 18.7, 37.5, 75, and 150 nM) of MMP-1/TIMP-1 complex were injected over the LRP1-coated surface.

    Recombinant LRP1 fragments of either Cluster II, III, or IV were immobilized to three individual flow cells of a CM5 sensor chip using an amine-reactive coupling process. SPR experiments tested binding of proMMP-1 (A) or TIMP-1 (B) to Cluster II (orange), III (blue), and IV (gray) with increasing concentrations of ligand (proMMP-1: 0.29, 0.58, 1.17, 2.34, 4.68, 9.38, 18.75, 37.5, 75, and 150 nM; TIMP-1: 0.58, 1.17, 2.34, 4.68, 9.38, 18.75, 37.5, 75, 150, and 300 nM). At each concentration, the binding association curves were fit to a pseudo-first order process. Req was estimated as the maximum number of response units at equilibrium for each concentration. Shown are the plots of Req versus ligand concentration. Data is plotted as mean ± SEM (n=3). The data were normalized to the amount of cluster coated on the CM5 sensor chip. GraphPad Prism 8.0 software was used to fit the data to the specific binding non-linear regression model to determine the KD of each ligand for each cluster. All calculated KD values are reported in Table 3.
