Monoclonal Antibodies: Principles and Practice, (3) (1996)

A new crystal form of MshB from Mycobacterium tuberculosis with glycerol and acetate in the active site suggests the catalytic mechanism.

Simon Gareth Broadley et al.

Acta crystallographica. Section D, Biological crystallography, 68(Pt 11), 1450-1459 (2012-10-24)

MshB, a zinc-based deacetylase, catalyses a step in the mycothiol biosynthetic pathway that involves the deacetylation of 1-O-(2-acetamido-2-deoxy-α-D-glucopyranosyl)-D-myo-inositol (GlcNAc-Ins), via cleavage of an amide bond, to 1-O-(2-amino-2-deoxy-α-D-glucopyranosyl)-D-myo-inositol (GlcN-Ins) and acetate. In this study, MshB was expressed, purified and crystallized. A

Redox sensor proteins for highly sensitive direct imaging of intracellular redox state.

Kazunori Sugiura et al.

Biochemical and biophysical research communications, 457(3), 242-248 (2015-01-17)

Intracellular redox state is a critical factor for fundamental cellular functions, including regulation of the activities of various metabolic enzymes as well as ROS production and elimination. Genetically-encoded fluorescent redox sensors, such as roGFP (Hanson, G. T., et al. (2004))

Inter-ring communication is dispensable in the reaction cycle of group II chaperonins.

Yohei Y Yamamoto et al.

Journal of molecular biology, 426(14), 2667-2678 (2014-05-27)

Chaperonins are ubiquitous molecular chaperones with the subunit molecular mass of 60kDa. They exist as double-ring oligomers with central cavities. An ATP-dependent conformational change of the cavity induces the folding of an unfolded protein that is captured in the cavity.

Secondary organic aerosol formation from acyclic, monocyclic, and polycyclic alkanes.

James F Hunter et al.

Environmental science & technology, 48(17), 10227-10234 (2014-08-06)

A large number of organic species emitted into the atmosphere contain cycloalkyl groups. While cyclic species are believed to be important secondary organic aerosol (SOA) precursors, the specific role of cyclic moieties (particularly for species with multiple or fused rings)
