Relationship between the Flotation Behavior of Lepidolite with Different Grain Sizes and the Crystal Anisotropy

Kuangchan zonghe liyong
[Objective] To clarify the adsorption behavior of the reagent on different crystal planes of lepidolite and the mechanism of flotation differences, [Method] three particle sizes of lepidolite, namely -75+38 μm, -38+23 μm, and -23 μm, were taken as the ...

Structural studies and functional engineering of NanX: an anhydro‐sialic acid transporter from Escherichia coli

FEBS Open Bio, EarlyView.
Biophysical characterisation shows that NanX, a membrane transport protein from the major facilitator superfamily (MFS), forms both monomers and dimers after purification. AlphaFold modelling and substrate docking provide information on residues likely involved in substrate recognition for NanX and another MFS member, NanT.

In silico and in vitro exploration of a tyrosinase for biocatalytic production of catechols

FEBS Open Bio, EarlyView.
Tyrosinase from Ralstonia pseudosolanacearum is a promising biocatalyst for producing valuable catechols from monophenol substrates. This tyrosinase is uniquely suited to this due to its high monophenolase : diphenolase ratio. We combined in silico docking and in vivo kinetic characterisation of this tyrosinase with 11 industrially relevant monophenols,
