Formation of proteinase products from prothrombin
variants. Reaction mixtures contained 1.4
μm IIVariant, 30
μm PCPS, 6 μm DAPA,
30 nm Va, and 0.2 nm Xa. The initial velocity
of S2238 hydrolysis was determined on aliquots withdrawn and
quenched at the indicated times and converted to the
concentration of proteinase formed as described under
“Experimental Procedures.” Data obtained
with IIWT (●), IIRR
(○), IIRGR (▴), or
II-1δ (▵) are illustrated.
The line was arbitrarily drawn.
