Engineered Y145C substitution mutation in endogenously GFP-tagged ahcy-1 locus. ahcy-1(Y145C) mutation mimics the pathogenic human mutation AHCY Y143C. ahcy-1(Y145C) mutants have a prolonged lifespan and are larger than control animals. ahcy-1(Y145C) mutants are fertile and produce a brood of laid and hatched eggs similar to control animals. ahcy-1(Y145C) mutants show a slight increase in SAH and a decrease in SAM levels, leading to an increased SAH to SAM ratio.
