Unusual cyanobacterial TCA cycles: not broken just different

As a fundamental energy-conserving process common to all living organisms, respiration is responsible for the oxidation of respiratory substrates to drive ATP synthesis. Accordingly, it has long been accepted that a complete tricarboxylic acid (TCA) cycle is necessary for respiratory energy producti...

Accordingly, it has long been accepted that a complete tricarboxylic acid (TCA) cycle is necessary for respiratory energy production. Cyanobacteria, similar to some other prokaryotes, appeared to have an incomplete TCA cycle because they lack the enzyme 2-oxoglutarate dehydrogenase (OGDH). However, it has recently been reported that the cycle can be completed by the action of two alternative enzymes. In this opinion article, we discuss the progress being made to elucidate the nature of the TCA cycles in cyanobacteria and plants and outline open questions concerning the functional significance of this unusual metabolic feature in a broader evolutionary context.Trends in Plant Science2018-09-03T17:17:56Z2018-09-03T17:17:56Z2012-09info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlepdfapplication/pdf13601385https://doi.org/10.1016/j.tplants.2012.05.005http://www.locus.ufv.br/handle/123456789/21590porv. 17, n. 9, p. 503- 509, september 2012Elsevier Ltd.info:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFVSteinhauser, DirkFernie, Alisdair R.Araujo, Wagner L.2024-07-12T06:03:37Zoai:locus.ufv.br:123456789/21590Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452024-07-12T06:03:37LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false
