Editing Mitochondrial matrix (section)

=== Enzymes ===
Enzymes from processes that take place in the matrix. The citric acid cycle is facilitated by [[pyruvate dehydrogenase]], [[citrate synthase]], [[aconitase]], [[isocitrate dehydrogenase]], [[α-ketoglutarate dehydrogenase]], [[succinyl coenzyme A synthetase|succinyl-CoA synthetase]], [[fumarase]], and [[malate dehydrogenase]].<ref name=":1" /> The urea cycle is facilitated by [[carbamoyl phosphate synthetase I]] and [[ornithine transcarbamylase]].<ref name=":5" /> β-Oxidation uses [[pyruvate carboxylase]], [[Acyl CoA dehydrogenase|acyl-CoA dehydrogenase]], and [[β-ketothiolase]].<ref name=":0" /> Amino acid production is facilitated by [[transaminase]]s.<ref name=":7" /> Amino acid metabolism is mediated by [[protease]]s, such as [[PITRM1|presequence protease]].<ref>{{Cite journal|last1=King|first1=John V.|last2=Liang|first2=Wenguang G.|last3=Scherpelz|first3=Kathryn P.|last4=Schilling|first4=Alexander B.|last5=Meredith|first5=Stephen C.|last6=Tang|first6=Wei-Jen|date=2014-07-08|title=Molecular basis of substrate recognition and degradation by human presequence protease|journal=Structure|volume=22|issue=7|pages=996–1007|doi=10.1016/j.str.2014.05.003|issn=1878-4186|pmc=4128088|pmid=24931469}}</ref>
