Two recent studies... WebSep 9, 2024 · Now that the FXN activation mechanism is better understood, new approaches such as the development of molecules that exclude nonproductive mobile S-transfer loop conformations or stabilize the closed form of the cysteine desulfurase architecture might have potential as FXN replacement strategies and FRDA therapeutics.
WebJul 1, 1990 · The general applicability of the "cysteine-switch" activation mechanism to the members of the matrix metalloproteinase (MMP) gene family is examined here. All currently known members of the MMP gene family share the characteristic that they are synthesized in a latent, inactive, form. Recent evidence suggests that this latency in human ... WebThe cysteine synthase complex is consisted of two enzymes, serine acetyltransferase and OAS (thiol)lyase, and is tightly controlled by the sulfur status (Berkowitz et al., 2002; Droux et al., 1998; Wirtz and Hell, 2006 ). The cysteine synthase complex can dissociate in the presence of excess OAS.
