Ligases: Ligases are biological catalysts that catalyze the combination of two large molecules by forming a new chemical bond. The enzyme classification of ligases is based on their mechanism including ligases used to form carbon-oxygen, carbon-sulfur, carbon-nitrogen, carbon-carbon, phosphoric ester...
The identities of the important ubiquitin-protein ligases in skeletal muscle, and the ways in which they recognize substrates are still largely unknown. Recent in-vitro studies have suggested that one set of ubquitination enzymes, E2(14K) and E3(alpha), which are responsible for the 'N-end ...
What are DNA ligases? How do these enzymes participate in recombinant DNA technology? Are the following enzymes involved in DNA replication, transcription, or both? 1. DNA polymerase 2. RNA polymerase 3. DNA ligase In retroviruses, DNA is synthesized from an RNA template using which enzyme?
Photoreceptor-mediated control of E3 ubiquitin ligases such as CONSTITUTIVELY PHOTOMORPHOGENIC 1 (COP1)/SUPPRESSOR OF PHYA-105 (SPA) determines the abundance of TFs acting downstream in light-signalling pathways (e.g. ELONGATED HYPOCOTYL 5 (HY5) and B-box proteins (BBX)) but also of MBW ...

The six classes of enzymes are oxidoreductases, transferases, hydrolases, lyases, isomerases and ligases. They’re generally named for the types of reactions they catalyze. We produce a wide range of enzyme types within most of these classes. Our enzymes help make more than 30 industries more...
KCTD7 has been shown to directly interact with Cullin-3, a component of E3 ubiquitin-protein ligases that selectively tag proteins for degradation by the proteasome [260]. Staropoli et al. determined that the KCTD7 mutation originally described for CLN14 disease by them, which is not in the...
Enzymes are classified into six categories according to the type of reaction catalyzed: Oxidoreductases, transferases, hydrolases, lyases, ligases, and isomerases. Structurally, the vast majority of enzymes are proteins. Also RNA molecules have catalytic activity (ribozymes). What is enzyme catalysis...
Recently, two other ubiquitin ligases were shown to act upon the p53 protein, COP-1 and PIRH-2.19, 20 Why is this redundancy employed? What are the roles of these enzymes for the many diverse stress inputs, in different tissue or cell types or at the different times in development of...
DNA ligase catalyzes the formation of phosphodiester bonds between DNA strands. There are different types of DNA ligases found in viruses, bacteria, and mammalian cells.DNA ligase plays a crucial role in Recombinant DNA technology, in vitro study of Molecular Biology and Genetics ...
