Adenosine deaminase 2 (ADA2) has been identified as a regulator of toll-like receptor 9 (TLR9) activation in response to nucleic acids, according to a recent study. ADA2, previously known for its ...

这种抑制叫反馈抑制(feedback inhibition)。例如由苏氨酸生物合成为异亮氨酸，要经过5步，反应第一步有苏氨酸脱氨酶(threonine deaminase)催化，当终产物异亮氨酸浓度达到足够水平时，该酶就被抑制，异亮氨酸结合到酶的一个调节部位上，通过可逆的别够作用对酶产生 ...
