Protein translocation functions of Escherichia coli SecY: in vitro characterization of cold-sensitive secY mutants.

Biochimie - 1 Sept 1997

Taura T, Yoshihisa T, Ito K

Abstract excerpt

Protein translocation across the plasma membrane of E coli is facilitated by Sec factors, including the membrane-embedded SecYEG subunit and the SecA ATPase. Although there is complete agreement that SecA is essential for protein translocation, some publications question the essentialness of SecY. We previously isolated a number of cold-sensitive mutants of secY and characterized their in vivo phenotypes. In this...
