The conserved surface cysteines of PR10-10 and their possible linkages. (a) The PR10-10 homodimer as represented by the crystal structure of apo PR10-10 (PDB: 7uql) and its surface cysteines (Cys21, Cys59 and Cys155). (b) Diagram illustrating the observed disulfide bond mediated oligomerization of PR10-10 (black) and additional hypothetical disulfide bonds formed by other surface cysteines (red and purple). The hypothetical possibility of PR10 heterodimers is indicated using a grey protomer. PR10-10 protomers are shown in green and cyan.
