Amino acid transport and protein synthesis in induced ectoderm of amphibian embryos

  • Wilhelm Minuth

Isolated gastrula ectoderm ofTriturus alpestris orAmbystoma mexicanum was induced by the vegetalizing factor. Protein synthesis in the induced and uninduced control explants was measured by double labelling with3H-and14C-amino acids after different periods of cultivation. Slight differences were observed in the pattern of nuclear proteins after 12 h of cultivation and in the pattern of cytoplasmic proteins after 48 h of cultivation.

The uptake of leucine started to increase in induced explants after 48 h of cultivation and after 96 h was about 50 times greater than in uninduced control explants. The uptake is reduced under partially anaerobic conditions. Ouabain inhibits the uptake by about 50%.
