TABLE 1.

Quantification of the RbcL and CpcB^∗IFN fusion proteins as percent of the total Synechocystis proteins loaded onto the SDS-PAGE lanes of Figure 5.

Protein measured	CpcB∗ IFN’ 1	CpcB∗ IFN’ 2	CpcB∗ IFN’ 3	CpcB∗ IFN 1	CpcB∗ IFN 2	CpcB∗ IFN 3
RbcL	12.1	12.4	13.2	11.9	12.9	12.6
CpcB∗IFN	10.4	9.9	10.2	11.8	11.9	11.7

RbcL levels were measured to account for ∼12.5 ± 0.5%, CpcB^∗IFN’ accounted for 10.2 ± 0.2%, whereas the CpcB^∗IFN accounted for 11.8 ± 0.1% of the total cellular proteins.
