Diversity and similarity in the tRNA world: overall view and case study on malaria-related tRNAs.

abstract：:It is known that a high incidence of hepatocellular carcinoma in rat liver can be induced by such azo dye carcinogens as 3'-methyl-4-dimethylaminoazobenzene (3'-MeDAB). Mammalian S-adenosylmethionine (AdoMet) synthetase exists as two isozymes, non-hepatic-type and liver-type enzymes, which are the products of two diff...
