- who: Zachary Armstrong from the Structural Biology Laboratory University of York, Heslington, York , DD, UK have published the research: Cryo-EM structures of human fucosidase FucA1 reveal insight into substrate recognition and catalysis, in the Journal: (JOURNAL)
- what: This work has conclusively identified the hitherto contentious identity of the catalytic acid/base as aspartate-276 representing a shift from both the canonical glutamate acid/base residue and a previously proposed glutamate residue.
- how: As this protein is naturally glycosylated (Alhadeff et_al 1975) the authors chose to express it in eukaryotic Trichoplusa ni (that . . .
