Table 2.

Calculated theoretical isoelectric points of matrix and IMS localised domains of Cox14p, Coa1p, and Coa3p using “ExPASy compute pI/MW” tool. Red and light blue indicate pI of domain in > 1 pH unit lower or higher than overall protein pI.

Coa1p	10.94 N	5.66 C	5.52	10.12
Coa3p	5.48 C	11.07 N	8.43	9.83
