TI  - Bound structures of novel P3-P1' beta-strand mimetic inhibitors of thrombin.
PG  - 1376-83
AB  - The X-ray crystal structures of four beta-strand-templated active site inhibitors
      of thrombin containing P1' groups have been determined and refined at about 2.1-A
      resolution to crystallographic R-values between 0.148 and 0.164. Two of the
      inhibitors have an alpha-ketoamide functionality at the scissile bond; the other 
      two have a nonhydrolyzable electrophilic group at the P1' position. The binding
      of lysine is compared with that of arginine at the S1 specificity site, while
      that of D,L-phenylalanine enantiomorphs is compared in the S3 region of thrombin.
      Four different P1' moieties bind at the S1' subsite in three different ways. The 
      binding constants vary between 2.0 microM and 70 pM. The bound structures are
      used to intercorrelate the various binding constants and also lead to insightful 
      inferences concerning binding at the S1' site of thrombin.
