Cleavage of the register shift prothrombin variants by
prothrombinase. Experimental conditions, reactant
concentrations, and reaction times were identical to those
presented in the legend for Fig.
1 except that the variants analyzed were different. The
stained gels illustrate the fate of IIRGR
(A), II-1δ
(B), II-2δ
(C), II-3δ
(D), II-4δ
(E), and IIQ320 (F)
following the addition of prothrombinase. Identities of the
polypeptide species are denoted in the margins.
