Amino Acid Sequence of an Unique Ribonuclease with a C-Terminus rich in O-Glycosylated Serine and Threonine from Culture Medium of Lentinus edodes

概要

論文の詳細を見る
The mushroom Lentinus edodes produces three basenon-specific and acid ribonucleases, RNases Le2,Le37,and Le45. The latter two are excreted from mycelia into the medium. The primary structure of RNase Le37,which had a molecular mass of 37 kDa, was sequenced. It was a member of the RNase T2 family, as is RNase Le2. RNase Le37 was some 30 amino acid residues longer at the C-terminal end than RNase Le2. The Cterminal region of RNase Le37 was rich in Oglycosylated serine and threonine. In fungal glucoamylases and chitinases, which hydrolyze raw-starch and chitin, respectively, have structures resembling the structure of the C-terminal of RNase Le37.
