Inhibition of the MeSA esterase activity of SABP2 by SA.
Lines represent the global fit of all data (n = 3) to the
equation for competitive inhibition. Initial velocities were determined as
described under “Experimental Procedures” at 0 μm
(open circles), 1 μm (open squares), 2.5
μm (open triangles), 5 μm (closed
circles), 10 μm (closed squares), and 50
μm (closed triangles) SA.
