Abstract

Alternativna oksidaza nalazi se u dišnom lancu mitohondrija biljaka, a također i u nekim plastidima kao što su kloroplasti. Nije prisutna samo u biljkama, kao što se prvotno mislilo, već je dokazana i u nekim životinjama. Ekspresija alternativne oksidaze usko je povezana s pojavom različitih stresnih uvjeta što dovodi do zaključka da doprinosi otpornosti na takve uvjete, ali i zaštiti biljnog tkiva od štetnih učinaka reaktivnih oblika kisika. Pretpostavlja se da se tijekom evolucije razvila kao prilagodba na nove životne uvjete u kojima su se našli biljni, ali i životinjski organizmi prilikom prilagodbe na život na kopnu. Danas je poznat velik broj biljnih, ali i neki životinjski organizmi, u kojima je zastupljena pa se pretpostavlja se da će se daljnjim istraživanjima upotpuniti saznanja o njezinoj ulozi.

Abstract (english)

Alternative oxidase is a component of mitohondrial respiratory chain in plants, but it is also found in some plastids such as chloroplasts. It is not only present in plants, as it was originally meant. It is already found in some animals. Expression of alternative oxidase is closely associated with various stress conditions, which leads to the conclusion that it is important in survival in such conditions, but also in protecting plant tissues from the harmful effects of reactive oxygen species. It is supposed that it was developed during evolution as an adaptation of plant and animal organisms to life on land. Today it known that alternative oxidase is present in a great number of plant species and also in some animal oragnisms. It could be expected that the knowledge about its role will be completed in further investigations.
