Abstract

Infiltration experiments with the intact seeds of Bengal gram (Cicer arietinum) indicated that indole and serine are the immediate precursors of tryptophan in this legume. The enzyme, tryptophan synthetase, has been demonstrated in cell-free extracts of the resting seeds. The optimum pH of the reaction was 5.5, and the Km value for indole at a constant serine concentration of 10−4M was 0.57 × 10−4M. There was a specific requirement for pyridoxal phosphate. Heavy-metal ions were inhibitory.
