WebApr 1, 2002 · The magnitude of TS affinity for O-phosphohomoserine also appears to be highly regulated. In vitro biochemical studies showed that the TS affinity for O-phosphohomoserine is stimulated by SAM, an immediate product of methionine 13., 16.. This suggests that methionine regulates its own synthesis through SAM.
