Figure 6. Alba2 and Alba3 partially associate with polysomes.

Figure 6

(A) Protein extracts from wild type AnTat1.1 were separated on sucrose gradients. Absorption at 254 nm was recorded during fractionation of the gradient. Fractions were separated by SDS-PAGE and analyzed by immunoblotting. The ribosomal protein P0 served as a ribosome marker and the endoplasmic reticulum protein BiP as a marker for proteins not associated with ribosomes. (B) Fractionation of extracts after treatment with 50 mM EDTA, which disrupts polysomes.
