Cancer Research
Breast cancer is one of the leading causes of death among women. Expression of different proteins, such as hormone receptors (HR), are used to classify different types of breast cancer (i.e., HR+BC or triple negative breast cancer (TNBC)).

Serine metabolism in legume nodules: Purification and properties of phosphoserine aminotransferase
Physiologia Plantarum, 1988Enzymes involved in serine metabolism were compared in the plant cytosol fraction of root nodules from soybean [Glycine max (L.) Merr., cv. Amsoy] and lupin [Lupinus angustifolius L., cv. Uniharvest]. Soybean nodules are ureide exporters and have a serine requirement in the synthesis of these compounds, whereas lupin nodules are amide transporters and ...

The primary structure of the aspartate aminotransferase (AspAT) of an archaebacterium, Methanobacterium thermoformicicum strain SF-4, has been determined by cloning and sequencing of the gene for the enzyme. The gene had a consensus promoter and a ribosome binding sequence of methanogens in the 5' untranslated region, followed by an open reading frame ...

Crystallographic and Solution Studies on Phosphoserine Aminotransferase (PSAT) from E.coli
1987Phosphoserine aminotransferase from E.coli has been crystallized in space group P212121, with one ∝2 dimeric molecule per asymmetric unit. Single crystal microspectrophotometric measurements have shown that the enzyme is catalytically active in the crystal.

Two peaks of aspartate aminotransferase (AspAT) catalytic activity were observed during DEAE chromatography of a protein extract from alkalophilic B. circulans. The enzyme purified from the major peak appeared to be not aspartate but phosphoserine aminotransferase (PSAT) with a considerably high AspAT side activity.
