    Figure 2. Inhibition of ADAMTS1 by TIMPs. A, inhibition of versicanase activity by TIMP family members. <t>TIMP1,</t> TIMP2, TIMP3, and TIMP4 (each at 500 nM) were incubated with ADAMTS1 (100 nM) for 1 h at 37 C before addition of V1-5GAG and digestion for 2 h. Following SDS-PAGE under reducing conditions (5% β-mercaptoethanol) and immunoblotting, FL V1-5GAG and versikine (VSK) were detected by the anti-Vc antibody. A representative immunoblot is shown (n = 2 independent experiments). B, inhibition of peptidolytic activity. TIMPs (each 25 nM) were incubated with a nominal con- centration of 25 nM ADAMTS1 for 1 h at 37 C before addition of the QF peptide substrate fluorescein-5(6)-carbonyl-Ala-Glu-Leu-Asn-Gly-Arg-Pro-Ile-Ser-Ile- Ala-Lys (5(6)-TAMRA) (3.5 μM) and digestion for 2 h. Following subtraction of the background (reactions not containing ADAMTS1), values were converted into percentage of ADAMTS1 activity in the absence of TIMPs and reported as average ± SD (n = 3, each point representing a technical replicate), p < 0.05 by Mann-Whitney test. C, titration of ADAMTS1 with TIMP3. TIMP3 (0–16 nM) was incubated with ADAMTS1 (20 nM nominal concentration) at 37 C for 1 h, and residual activity against the QF peptide FAM-AELNGRPISIAK-Tamra (3.5 μM) was determined. A representative titration curve is shown, each point representing a mean of two technical replicates. Final concentration of ADAMTS1 following titration was 10 nM. FL, full-length; No E, no enzyme; No I, no inhibitor; QF, Quenched-Fluorescent; TIMP, tissue inhibitor of metalloproteinase.
