Fig. 5. Crystallographic dimer in PSA and HPK. (a) The dimer for PSA. The kallikrein loop is shown in dark green, the substrate in light green sticks and the carbohydrate moieties in CPK (beige and red). (b) PSA dimer (yellow and pink as in a) and crystal contacts with the antibody heavy chain (dark blue) showing the relationship between the substrate (CPK, light green) and the CH1 domain C-terminus bound by PSA (dark blue sticks). (c) The dimer for HPK.
