The dependence of shugoshin on Bub1-kinase activity is dispensable for the maintenance of spindle assembly checkpoint response in Cryptococcus neoformans

This study shows that Sgo1 maintains SAC signals in Cryptococcus neoformans by regulating Aurora B kinase and PP1 levels at kinetochores, independent of Bub1 kinase activity.

Mechanistic insights into the functioning of GMP synthetase: a two-subunit, allosterically regulated, ammonia tunnelling enzyme

This paper presents a mechanistic model of MjGMPS, a two-subunit GMP synthetase, using biochemical experiments, crystal structures, and cross-linking mass spectrometry to elucidate ammonia tunneling and allostery.
