Serine hydroxymethyltransferase from spinach leaf mitochondria. Purification and characterization

Abstract: A mitochondrial serine hydroxymethyltransferase (EC 2.1.2.1) has for the first time been purified close to homogeneity from a photosynthetically active tissue, spinach (Spinacea oleracea L. cv Viking II) leaves. The specific activity of the enzyme was 7.8 μmol (mg protein)−1 min−1 using L‐serine as substrate. The enzyme was stable for at least 8 weeks at 4°C in the presence of folate. The pH optimum was at pH 8.5 where the enzyme had a Km for L‐serine of 0.9 mM. Carboxymethoxylamine was a strong competitive in… Show more
