If the atmosphere of the early Earth was hydrogen-rich, 1 it is reasonable to think that
hydrogenases, the enzymes enabling cells to use molecular hydrogen, were probably …

Carotenoids represent a large class of terpenoids characterized by an extensively
conjugated polyene chain. The conjugation system imparts carotenoids with excellent light …

In Escherichia coli, the main player in transcription regulation of fatty acid metabolism is the
FadR protein, which is involved in negative regulation of fatty acid degradation and in …

SUMMARY Iron-sulfur (Fe-S) clusters are required for critical biochemical pathways,
including respiration, photosynthesis, and nitrogen fixation. Assembly of these iron cofactors …

Broadly neutralizing antibodies (bNAbs) against HIV-1 Env V1V2 arise in multiple donors.
However, atomic-level interactions had previously been determined only with antibodies …

Membrane phospholipid synthesis is a vital facet of bacterial physiology. Although the

ABSTRACT The 37/67‐kDa laminin receptor (LAMR/RPSA) was originally identified as a 67‐
kDa binding protein for laminin, an extracellular matrix glycoprotein that provides cellular …

The 67LR (67 kDa laminin receptor) is a cell-surface receptor with high affinity for its primary
ligand. Its role as a laminin receptor makes it an important molecule both in cell adhesion to …
