Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

FEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

FEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Compressibility of pyrochlore-type MgZrSi2O7 determined by in situ X-ray diffraction in a large-volume high pressure apparatus

, 2013
The pyrochlore-type MgZrSi2O7 has been investigated by in situ synchrotron energy-dispersive X-ray diffraction measurements up 24.3GPa at room temperature in a multianvil high pressure apparatus.

Experimental evidence for a shallow cumulate remelting origin of lunar high-titanium mare basalts

Communications Earth & Environment
High-titanium mare basalts were among the earliest rocks to be returned from the Moon, but key aspects of their formation remain enigmatic. Here we show twenty partial remelting experiments conducted on three bulk compositions based on shallow ilmenite ...

T1–T2 microscale correlation relaxometry for in situ high-pressure nuclear magnetic resonance [PDF]

Matter and Radiation at Extremes
Over the last decade, frequency-domain in situ high-pressure nuclear magnetic resonance (NMR) spectroscopy in diamond anvil cells (DACs) has been employed as a structural and electronic probe of condensed matter systems at pressures well into the megabar

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

FEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

In situ high-pressure vulcanization and thermal properties of polyisoprene

, 2006
Liquid cis-1,4-poly(isoprene) (PI) has been vulcanized under high pressures without using additives. Moreover, the thermal conductivity and heat capacity per unit volume of both unvulcanized (liquid state at room temperature) and vulcanized (rubbery ...
