Mung bean nuclease has an estimated molecular weight of 39 kDa by SDS-PAGE. A glycoprotein, 29% of this mass is sugars. , the specific gene encoding for this protein is unknown, and all production relies on a purification process on bean sprouts from 1980. Some is known about its structure, with one exposed Cysteine residue and 3 pairs of disulfide bonds. Some is known about its amino acid composition.
