TPS1 is an enzyme putatively involved in trehalose biosynthesis. It has a trehalose synthase (TPS)-like domain but no trehalose phosphatase (TPP)-like domain.
HCF107 is involved in regulating plastidial gene expression and biogenesis. HCF107 binding remodels the structure of the psbH 5′ UTR in a way that can account for its ability to enhance psbH translation.
AFH1 is a nonprocessive formin that moves from the barbered end to the side of an actin filament after the nucleation event. It might be involved in the organization and polarity of the actin cytoskeleton. And AFH1 is involved in polar pollen cell growth process by maintaining tip-focused cell membrane expansion for the polar extension of pollen tubes.
AKR4C8 is an NADPH-dependent aldo-keto reductase that can act on a wide variety of substrates in vitro including aliphatic and aromatic aldehydes and steroids.
Cytochrome c oxidase is the last enzyme in the respiratory electron transport chain of mitochondria and it is also called Complex IV. Cytochrome c oxidase receives an electron from each of four cytochrome c molecules, and transfers them to one oxygen molecule, converting molecular oxygen to two molecules of water. In higher plants mitochondria, Complex IV processes 14 subunits. COX Vb (AT3G15640/AT1G80230) is one subunit of the Complex IV.
Malate dehydrogenase (MDH) catalyzes a reversible NAD(+)-dependent-dehydrogenase reaction involved in central metabolism and redox homeostasis between organelle compartments.
