Protein engineering by resurfacing is an efficient approach to provide new molecular toolkits for biotechnology and bioanalytical chemistry. H39GFP is a new variant of green fluorescent protein (GFP) containing 39 histidine residues in the primary sequence that was developed by protein resurfacing. Herein, taking H39GFP as the signal reporter, a label-free(More)
The preprotein translocase of the inner membrane of mitochondria (TIM23 complex) is the main entry gate for proteins of the matrix and the inner membrane. Tim50 is a major receptor for transporting the precursor protein across the mitochondrial inner membrane in the TIM23 complex. However, the interaction of prequence peptide with Tim50 is not well-known.(More)
The preprotein translocase of the inner membrane of mitochondria (TIM23 complex) is the main entry gate for proteins of the matrix and the inner membrane. Tim23p, the core component of TIM23 complex, forms the import pore across the inner membrane. However, the interaction between presequence peptides and Tim23p remains unclear. Herein, we investigated the(More)

Tim50 is a major receptor for transporting the precursor protein across the mitochondrial inner membrane in TIM23 complex. However, the interaction of divalent metal ions with Tim50 and the contribution(More)
The preprotein translocase of the inner mitochondrial membrane (TIM23 complex) is the main entry gate for proteins of the matrix and the inner membrane. Tim23 forms a pore for preprotein transportation in TIM23 complex, which spans the inner membrane with transmembrane segments and exposes a hydrophilic domain in the intermembrane space. In this study, we(More)
The preprotein translocase of the inner membrane of mitochondria (TIM23 complex) is the main entry gate for proteins of the matrix and the inner membrane. Tim23p, the core component of TIM23 complex, forms the import pore across the inner membrane and exerts a key function in the protein import. However, the interaction of divalent metal ions with Tim23p(More)
