Regulatory subunit of the trehalose synthase complex that catalyzes the production of trehalose from glucose-6-phosphate and UDP-glucose in a two step process. May stabilize the trehalose synthase complex, and confer sensitivity to physiological concentrations of phosphate and to fructose 6-phosphate.
Positively regulates the activity of the minus-end directed microtubule motor protein dynein. Plays a central role in positioning the mitotic spindle at the bud neck during cell division. Targets cytoplasmic dynein to microtubule plus ends, thereby promoting dynein-mediated microtubule sliding along the bud cortex and consequently the movement of the mitotic spindle to the bud neck. Following plus end binding, dynein may be offloaded to the cortex by NUM1. Required for viability in the absence of the kinesin-related microtubule-dependent motor protein CIN8.
Catalyzes the irreversible cleavage of the glycosidic bond in both 5'-methylthioadenosine (MTA) and S-adenosylhomocysteine (SAH/AdoHcy) to adenine and the corresponding thioribose, 5'-methylthioribose and S-ribosylhomocysteine, respectively. Can also use 5'-isobutylthioadenosine, 5'-n-butylthioadenosine, S-adenosyl-D-homocysteine, decarboxylated adenosylhomocysteine, deaminated adenosylhomocysteine and S-2-aza-adenosylhomocysteine as substrates.
Catalyzes the dephosphorylation of 5-amino-6-(5-phospho-D-ribitylamino)uracil, and thus could be involved in the riboflavin biosynthesis pathway (PubMed:24123841). Is also able to dephosphorylate flavin mononucleotide (FMN) and other phosphoric acid esters (PubMed:16990279) (PubMed:24123841). YigB is important for the formation of dormant persister cells (PubMed:18519731).
(+)-Neomenthol dehydrogenase is an enzyme found in the cytosol that catalyzes a reaction in monoterpenoid biosynthesis whereby (-)-menthone is converted into (+)-neomenthol.
(2E,6E)-farnesyl diphosphate synthase is an enzyme found in the cytosol, chloroplast, and mitochondria that catalyzes a reaction in both the epoxysqualene biosynthesis and farnesene biosynthesis pathways whereby geranyl diphosphate is converted into farnesyl diphosphate. In Arabidopsis thaliana, there appears to be several different enzymes could catalyze this reaction, each encoded by differentially expressed genes.
(E,E)-alpha-farnesene synthase is an enzyme in the cytosol that catalyzes a reaction in the farnesene biosynthesis pathway whereby farnesyl diphosphate is converted into (E,E)-alpha-farnesene. In Arabidopsis thaliana, (E,E)-alpha-farnesene synthase is encoded by 2 differentially expressed genes (TPS02, TPS03). It requires a magnesium or manganese ion as cofactors.
