Data collection and refinement statistics for the textilinin-1 complexes.

aValues in parentheses are for the outer resolution shells 2.89–2.78 Å, and 1.69–1.64 Å for the microplasmin and trypsin complexes, respectively. bRsym = Σh Σi | Ih,i - Ih>|/Σh Σi I h,i where Ih,i is the intensity of the ith measurement of reflection h and Ih> is the average value over multiple measurements. cRwork = Σ||Fobs|-|Fcalc||/Σ|Fobs|, Rwork is calculated based on the reflections used in the refinement (95% of the total data) and Rfree is calculated using the remaining 5% of the data.
