complexes,ventricular premature 《英文msh詞典》Complexes,Ventricular Premature ; [入口詞] Complexes,Ventricular Premature ; [主題詞] Ventricular Premature Complexes ; [英文釋義] Premature contractions of the ventricle,the most common of all arrhythmias. In the absence of heart disease,they are not of great clinical significance,but in patients with coronary disease,they represent a constant danger of ventricular tachycardia or fibrillation and sudden death. The longer-term prognosis for asymptomatic,healthy subjects with frequent and complex ectopy is similar to that for the healthy United States population.

complexes,ubiquitin-protein ligase 《英文msh詞典》Complexes,Ubiquitin-Protein Ligase ; [入口詞] Complexes,Ubiquitin-Protein Ligase ; [主題詞] Ubiquitin-Protein Ligase Complexes ; [英文釋義] Complexes of enzymes that catalyze the covalent attachment of UBIQUITIN to other proteins by forming a peptide bond between the C-terminal GLYCINE of UBIQUITIN and the alpha-amino groups of LYSINE residues in the protein. The complexes play an important role in mediating the selective-degradation of short-lived and abnormal proteins. The complex of enzymes can be broken down into three components that involve activation of ubiquitin (UBIQUITIN-ACTIVATING ENZYMES),conjugation of ubiquitin to the ligase complex (UBIQUITIN-CONJUGATING ENZYMES),and ligation of ubiquitin to the substrate protein (UBIQUITIN-PROTEIN LIGASES).
