SDS/urea–PAGE (a) and tricine SDS–PAGE (b) profiles of purified PSII dimer from wild type (left lane) and mutant (right lane). The subunit names are indicated on the right side of the panel. The arrows indicate the 4.7 kDa band corresponding to the PsbTc subunit. The arrowhead in (b) indicates the band corresponding to PsbTc lacking its C-terminal loop. |
