The structure of rice weevil pectin methylesterase. [PDF]

Acta Crystallogr F Struct Biol Commun, 2014
Rice weevils (Sitophilus oryzae) use a pectin methylesterase (EC 3.1.1.11), along with other enzymes, to digest cell walls in cereal grains. The enzyme is a right-handed β-helix protein, but is circularly permuted relative to plant and bacterial pectin methylesterases, as shown by the crystal structure determination reported here.

First confirmation of the distribution of rice weevil, Sitophilus oryzae, in South Korea

Journal of Asia-Pacific Biodiversity, 2018
In Korea, the classification of the Sitophilus weevil group occurring in stored grains has been confused, resulting in its misidentification in most references reporting Sitophilus oryzae (Linnaeus). However, we recently found and identified rice weevil (
