Fig. 7From: Chloroplast PetD protein: evidence for SRP/Alb3-dependent insertion into the thylakoid membraneMALDI-TOF mass spectra. Mass spectrum was obtained after isolation of PetD and PetB crosslinked (SPDP) complexes from thylakoid membranes followed by immunoprecipitation and cleavage with 25 mM DDT solution [12]. The unconjugated proteins solution was analysed by MALDI-TOF. The intensity (peak height on the y-axis) of the resulting MALDI spectrum is not quantitativeBack to article page
