In vivo evidence for glycyl radical insertion into a catalytically inactive variant of pyruvate formate‐lyase

open access: yesFEBS Letters, EarlyView.
Dimeric pyruvate formate‐lyase cleaves pyruvate using a radical‐based mechanism. G734 serves as a radical storage location, and the radical is transferred to the catalytic C419 residue. Mutation of the C418‐C419 pair causes loss of enzyme activity, but does not impede radical introduction onto G734. Therefore, cis‐ but not trans‐radical transfer occurs

Hydroponic pepper growing on baked clay pellets

open access: yesInternational Journal of Horticultural Science, 2006
Nowadays one of the most important issues of greenhouse vegetable production in soilless media is the protection of the environment, in particular, the selection of the root medium to be applied.

Torsion pairs and rigid objects in tubes [PDF]

open access: yes, 2011
We classify the torsion pairs in a tube category and show that they are in bijection with maximal rigid objects in the extension of the tube category containing the Pruefer and adic modules. We show that the annulus geometric model for the tube category can be extended to the larger category and interpret torsion pairs, maximal rigid objects and the ...

Exceptional hyperbolic 3-manifolds [PDF]

open access: yesCommentarii Mathematici Helvitici, Vol. 90, 3 (2015), 703-730, 2013
We correct and complete a conjecture of D. Gabai, R. Meyerhoff and N. Thurston on the classification and properties of thin tubed closed hyperbolic 3-manifolds. We additionally show that if N is a closed hyperbolic 3-manifold, then either N=Vol3 or N contains a closed geodesic that is the core of an embedded tube of radius log(3)/2.

A coiled‐coil domain triggers oligomerization of MmpL10, the mycobacterial transporter of trehalose polyphleate precursor

open access: yesFEBS Letters, EarlyView.
Most MmpLs transport lipids and glycolipids of the complex mycomembrane of mycobacteria. This study shows that MmpL10 from Mycobacterium smegmatis, the transporter of the trehalose polyphosphate precursor, harbors a coiled‐coil‐like extension. Biochemical and electron microscopy studies demonstrate that the coiled‐coil enables MmpL10 to trimerize.

Influence of structural flexibility on the nonlinear stiffness of hydraulic system

open access: yesAdvances in Mechanical Engineering, 2016
Hydraulic system has been widely used in many mechatronic systems. Accurate identification of the hydraulic stiffness is critical to the design and control of such kind of system.

Effective distance between nested Margulis tubes [PDF]

open access: yesTrans. Amer. Math. Soc. 372 (2019), Issue 6, 4211-4237, 2018
We give sharp, effective bounds on the distance between tori of fixed injectivity radius inside a Margulis tube in a hyperbolic 3-manifold.
