ABSTRACT
The use of an amino acid analyser for the detection of hydroxyproline in Dictyostelium discoideum was misleading because of the low sensitivity of the instrument toward the hydroxyproline and because of the low concentration of hydroxyproline in D. discoideum. A specific colorimetric method for hydroxyproline indicates that it is present in the slime mould and that the concentration decreases during differentiation
