Figure 3From: Synthetic signal sequences that enable efficient secretory protein production in the yeast Kluyveromyces marxianus Substitution of the hydrophobic stretch to eight repeats of single amino acids. Poly-Leu (L), Met (M), Trp (W), and Phe (F) increased the secretory luciferase activities, but other substitutions showed no activity levels. Data were shown as in Figure 2.Back to article page
