Figure 4
Effect of N -acetylchitoose concentration on GlcNAc incorporation. Different concentrations of N-acetylchito-tetra (A), -penta (B), -octaoses (C) were preincubated with membrane fractions before initiating the CHS reaction. GlcNAc incorporation into chitin versus N-acetylchitoose concentration is shown. AC50 corresponds to half-activating N-acetylchitoose concentration.
