[1] [2] [3] Enzymes known as site-specific recombinases (SSRs) perform rearrangements of DNA segments by recognizing and binding to short, specific DNA sequences (sites), at which they cleave the DNA backbone, exchange the two DNA helices involved, and rejoin the DNA strands. In some cases the presence of a recombinase enzyme and the ...

Aspartate carbamoyltransferase (also known as aspartate transcarbamoylase or ATCase) catalyzes the first step in the pyrimidine biosynthetic pathway (EC 2.1.3.2). [1]In E. coli, the enzyme is a multi-subunit protein complex composed of 12 subunits (300 kDa in total). [2]
This list contains a list of sub-classes for the seventh group of Enzyme Commission numbers, EC 7, translocases, placed in numerical order as determined by the Nomenclature Committee of the International Union of Biochemistry and Molecular Biology.
Regulatory enzymes are commonly the first enzyme in a multienzyme system: the product of the reaction catalyzed by the first enzyme is the substrate of the second enzyme, so the cell can control the amount of resulting product by regulating the activity of the first enzyme of the pathway.
Photosystem II, the first protein complex in the light-dependent reactions of oxygenic photosynthesis, contains a cytochrome b subunit. Cyclooxygenase 2, an enzyme involved in inflammation, is a cytochrome b protein. In the early 1960s, a linear evolution of cytochromes was suggested by Emanuel Margoliash [7] that led to the molecular clock ...
[1]: 8.1.3 Examples are lactase, alcohol dehydrogenase and DNA polymerase. Different enzymes that catalyze the same chemical reaction are called isozymes. [1]: 10.3 The International Union of Biochemistry and Molecular Biology have developed a nomenclature for enzymes, the EC numbers (for "Enzyme Commission"). Each enzyme is described by "EC ...
