... variable in the interaction with SRP [14,41,42]. However, the hydrophobicity of cysteine is even slightly lower than that of glycine [37]. Therefore, the cross-linking of (G-10C)prePhoE to P48 indicates ... hydrophobicity, resulting in a better interaction of the (G-10C)94PhoE protein with P48. The mechanism by which secretory proteins are routed into the SRP-targeting or the Se...
