Ligases are classified as EC 6 in the EC number classification of enzymes. Ligases can be further classified into six subclasses: EC 6.1 includes ligases used to form carbon-oxygen bonds; EC 6.2 includes ligases used to form carbon-sulfur bonds; EC 6.3 includes ligases used to form carbon-nitrogen bonds (including argininosuccinate synthetase)
EcoRI for example generates an AATT end, and since A and T have lower melting temperature than C and G, its melting temperature T m is low at around 6 ° C. [21] For most restriction enzymes, the overhangs generated have a T m that is around 15 ° C. [20] For practical purposes, sticky end ligations are performed at 12-16 ° C, or at room ...
DNA ligase is a type of enzyme that facilitates the joining of DNA strands together by catalyzing the formation of a phosphodiester bond.It plays a role in repairing single-strand breaks in duplex DNA in living organisms, but some forms (such as DNA ligase IV) may specifically repair double-strand breaks (i.e. a break in both complementary strands of DNA).
This enzyme belongs to the family of ATP-grasp ligases, specifically those forming carbon-nitrogen bonds as acid-D-amino-acid ligases (peptide synthases). The systematic name of this enzyme class is D-alanine:D-alanine ligase (ADP-forming). Other names in common use include alanine:alanine ligase (ADP-forming), and alanylalanine synthetase.
The long chain fatty acyl-CoA ligase (or synthetase) is an enzyme (EC 6.2.1.3) of the ligase family that activates the oxidation of complex fatty acids. [2] Long chain fatty acyl-CoA synthetase catalyzes the formation of fatty acyl-CoA by a two-step process proceeding through an adenylated intermediate. [3] The enzyme catalyzes the following ...
EC 6.3.2.19: The ubiquitinylation process is now known to be performed by several enzymes in sequence, starting with EC 6.2.1.45 (ubiquitin-activating enzyme E1) and followed by several transfer reactions, including those of EC 2.3.2.23 (E2 ubiquitin-conjugating enzyme) and EC 2.3.2.27 (RING-type E3 ubiquitin transferase)
