Abstract: Sirtuins (Sir2-like proteins) are present in prokaryotes and eukaryotes. Here, two new human sirtuins (SIRT6 and SIRT7) are found to be similar to a particular subset of insect, nematode, plant, and protozoan sirtuins. Molecular phylogenetic analysis of 60 sirtuin conserved core domain sequences from a diverse array of organisms (including archaeans, bacteria, yeasts, plants, protozoans, and metazoans) shows that eukaryotic Sir2-like proteins group into four main branches designated here as classes I-IV. Prokaryotic sirtuins include members of classes II and III. A fifth class of sirtuin is present in gram positive bacteria and Thermotoga maritima. Saccharomyces cerevisiae has five class I sirtuins. Caenorhabditis elegans and Drosophila melanogaster have sirtuin genes from classes I, II, and IV. The seven human sirtuin genes include all four classes: SIRT1, SIRT2, and SIRT3 are class I, SIRT4 is class II, SIRT5 is class III, and SIRT6 and SIRT7 are class IV. Copyright 2000 Academic Press.
