A PagP fusion protein system for the expression of intrinsically disordered proteins in E. coli
Download2012-01-01
Hwang, Peter M., Pan, Jonathan S., Sykes, Brian D.
PagP, a beta-barrel membrane protein found in Gram-negative bacteria, expresses robustly in inclusion bodies when its signal sequence is removed. We have developed a new fusion protein expression system based on PagP and demonstrated its utility in the expression of the unstructured N-terminal...

Structural and functional characterization of transmembrane segment IV of the NHE1 isoform of the na+/H+ exchanger
Download2005-01-01
Slepkov, Emily R., Rainey, Jan K., Li, Xiuju J., Liu, Yonghsheng S., Cheng, Florence J., Lindhout, Darrin A., Sykes, Brian D., Fliegel, Larry
The Na+/H+ exchanger isoform 1 is a ubiquitously expressed integral membrane protein that regulates intracellular pH in mammals. We characterized the structural and functional aspects of the critical transmembrane (TM) segment IV. Each residue was mutated to cysteine in cysteine-less NHE1. TM IV...

Structural and functional characterization of transmembrane segment VII of the na+/H+ exchanger isoform 1
Download2006-01-01
Ding, Jie, Rainey, Jan K., Xu, Caroline, Sykes, Brian D., Fliegel, Larry
The Na+/H+ exchanger isoform 1 is an integral membrane protein that regulates intracellular pH by exchanging one intracellular H+ for one extracellular Na+. It is composed of an N-terminal membrane domain of 12 transmembrane segments and an intracellular C-terminal regulatory domain. We...
