Import inhibition of the DHFR containing preprotein in mmp37Δ mitochondria can be relieved by extending the N-terminal region of the preprotein. The import of radiolabeled pSu9(1-79)DHFR (A) and pSu9(1-112)DHFR (B) preproteins into wild-type and mmp37Δ mitochondria was performed as described in Figure 6.
