| GO:0048269 | methionine adenosyltransferase complex | A multimeric enzyme complex composed of variable numbers of catalytic alpha subunits, and noncatalytic beta subunits. The beta subunits are believed to have a regulatory function. The enzyme complex catalyzes the synthesis of S-adenosylmethionine (AdoMet), which is the major methyl group donor, participating in the methylation of proteins, DNA, RNA, phospholipids, and other small molecules. | 1 |
| GO:0045261 | proton-transporting ATP synthase complex, catalytic core F(1) | The sector of a hydrogen-transporting ATP synthase complex in which the catalytic activity resides; it comprises the catalytic core and central stalk, and is peripherally associated with a membrane, such as the plasma membrane or the mitochondrial inner membrane, when the entire ATP synthase is assembled. | 1 |
| GO:0034657 | GID complex | A protein complex with ubiquitin ligase activity that is involved in proteasomal degradation of fructose-1,6-bisphosphatase (FBPase) and phosphoenolpyruvate carboxykinase during the transition from gluconeogenic to glycolytic growth conditions. In S. cerevisiae, the GID (Glucose Induced degradation Deficient) complex consists of Vid30p, Rmd5p, Vid24p, Vid28p, Gid7p, Gid8p, and Fyv10p. | 1 |
| GO:0017117 | single-stranded DNA-dependent ATP-dependent DNA helicase complex | A protein complex that possesses single-stranded DNA-dependent DNA helicase activity. | 1 |
| GO:0042575 | DNA polymerase complex | A protein complex that possesses DNA polymerase activity and is involved in template directed synthesis of DNA. | 1 |
| GO:0045264 | plasma membrane proton-transporting ATP synthase complex, coupling factor F(o) | All non-F1 subunits of the plasma membrane hydrogen-transporting ATP synthase, including integral and peripheral plasma membrane proteins. | 1 |
| GO:0031248 | protein acetyltransferase complex | A complex that catalyzes the transfer of an acetyl group to a protein acceptor molecule. | 1 |
| GO:0043626 | PCNA complex | A protein complex composed of three identical PCNA monomers, each comprising two similar domains, which are joined in a head-to-tail arrangement to form a homotrimer. Forms a ring-like structure in solution, with a central hole sufficiently large to accommodate the double helix of DNA. Originally characterized as a DNA sliding clamp for replicative DNA polymerases and as an essential component of the replisome, and has also been shown to be involved in other processes including Okazaki fragment processing, DNA repair, translesion DNA synthesis, DNA methylation, chromatin remodeling and cell cycle regulation. | 1 |
