Figure 2

Schematic representation of the domain composition of tomato PDI proteins. The putative signal peptides (SP), the a and b thioredoxin-like domains, the N-terminal calcium binding domain similar to calsequestrin, the D domain (Erp29c), the ERGIC_N domain, the C_ERV (COPII-coated ERV) domain, the Evr1_Air domain, the PAPS_reduct domain, and the transmembrane domain (TM) are displayed. The start and end boundaries of the a, b, and b’ domains, where two of the domain regions overlap, are marked by blue, green, and black hooks, respectively.
