应用
丝氨酸已被用作丝氨酰-tRNA 合成酶的抑制剂。 DL-丝氨酸异羟肟酸用于通过氨基酸饥饿诱导大肠杆菌中鸟苷 3′-二磷酸5′-二磷酸（ppGpp）的代谢合成。它还用于通过抑制 tRNA 装载来同步大肠杆菌培养物中的细胞周期。
生化/生理作用
丝氨酸参与单碳单位代谢。它与半胱氨酸、神经酰胺、磷脂酰丝氨酸、嘌呤和嘧啶的生物合成有关。在细菌中，它参与色氨酸合成。糖异生是重要的生化过程之一，涉及丝氨酸，尤其在反刍动物中。蛋白质磷酸化是利用丝氨酸的一种此类事件。甘氨酸是丝氨酸的代谢产物，可作为抗氧化剂和神经递质。已知 D-丝氨酸激活脑的 N-甲基-D-天冬氨酸（NMDA）受体。丝氨酸异羟肟酸，一种丝氨酸的结构类似物，它可阻止丝氨酸-tRNA（转移核糖核酸）装载，从而降低大肠杆菌的磷脂和核酸合成。

The stringent response is a mechanism by which bacteria adapt to nutritional deficiencies through the production of the guanine nucleotides ppGpp and pppGpp, produced by the RelA enzyme. We investigated the role of the relA gene in the ability of

The accumulation of RNA and protein and the kinetics of nucleoside triphosphate and guanosine polyphosphate pools during amino acid starvation and carbon source downshift were investigated in Streptomyces hygroscopicus. RNA accumulation was controlled stringently during both amino acid starvation and

During nutrient starvation, Escherichia coli elicits a stringent response involving the ribosome-associated protein RelA. Activation of RelA results in a global change in the cellular metabolism including enhanced expression of the stationary-phase sigma factor RpoS. In the human pathogen Pseudomonas
