Gs inhibition's

GS is subject to reversible covalent modification. Tyr of all 12 subunits can undergo adenylylation or deadenylylation by adenylyl transferase (AT), a bifunctional regulatory enzyme. Adenylylation is a post-translational modification involving the covalent attachment of AMP to a protein side chain. Each adenylylation requires an ATP and complete inhibition of GS requires 12 ATP. … WebMar 16, 2010 · The GS from Y30G01 and Y30G03 had a similar IC 50 for micafungin (138 and 385 mg/L, respectively) and for caspofungin (29 and 26 mg/L, respectively); these values were more than three log orders higher than those of the GS from TUA4 (Table 4). The inhibition curve for GS from the heterozygous Y30G strain was biphasic.
