Carboxylases are enzymes that incorporate carbon dioxide as a carboxy group into their substrate . The process they catalyze is called carboxylation . The process is ATP- dependent. You have biotin as a prosthetic group . Carboxylases ( EC 6.4.1.- ) mostly belong to the group of ligases .
Examples
The most common carboxylase is ribulose-1,5-bisphosphate carboxylase ( Rubisco ), an enzyme that binds carbon dioxide to ribulose-1,5-bisphosphate in the Calvin cycle of photosynthesis . Through this biochemical reaction, carbon dioxide is introduced from the water or from the air into the metabolism of photosynthesizing plants , protista or monera .
Other important carboxylases are:
plants
The PEP carboxylase is an essential switching point in the plant metabolism .
history
The carboxylase was discovered by the biochemist Carl Neuberg .
Other classes of enzymes
Enzymes that, unlike carboxylases, release carbon dioxide from their substrates are called decarboxylases .
