Description (originally from EcoCyc[1][2]) Signal Recognition Particle Protein Translocation System

Comments (originally from EcoCyc[1][2]) The Ffh/4.5S RNA/FtsY complex is believed to function in Escherichia coli in the targeting and integration of inner membrane proteins [3][4][5][6][7][3][8][9][4][6][6][10][11][12][13][14][15][16][17][18][19][20][10][10][21][22][10][23][24][25][26][27][28][29][30].
