Effects of five southern California macroalgal diets on consumption, growth, and gonad weight, in the purple sea urchin Strongylocentrotus purpuratus [PDF]
PeerJ, 2015 Consumer growth and reproductive capacity are direct functions of diet. Strongylocentrotid sea urchins, the dominant herbivores in California kelp forests, strongly prefer giant kelp (Macrocystis pyrifera), but are highly catholic in their ability to ...

5‐thiohistidine N‐acetyltransferase from Proteiniphilum saccharofermentans
ChemBioChem, Accepted Article.Ovothiol A is a 5‐thiohistidine derivative biosynthesized by a broad range of prokaryotic and eukaryotic organisms. Its redox‐active mercaptoimidazole side chain is believed to protect cells from oxidative stress. The three enzymes that produce ovothiol A from histidine, cysteine, and S‐adenosyl methionine have been identified and characterized.

Application of Metal‐Organic Framework Composites
ChemistryEurope, EarlyView.This review summarizes the applications of MOF composites in adsorption, energy storage, catalysis, biomedicine, and sensing. It also discusses the functionality of MOF composites from a dimensional perspective. Environmental issues have intensified, and demand for energy continues to grow, making it challenging for conventional materials to meet the ...

TRiC Is a Structural Component of Mammalian Sperm Axonemes
Cytoskeleton, EarlyView.ABSTRACT The TRiC chaperonin is responsible for folding ~5%–10% of the proteome in eukaryotic cells. Our recent cryo‐electron microscopy studies of axonemes from diverse mammalian cell types led to the surprising discovery that a fully assembled TRiC chaperonin is a structural component of mammalian sperm flagella, where it is tethered to the radial ...

Aggregative feeding behavior in sea urchins leads to destructive grazing in a Nova Scotian kelp bed
, 2012 Grazing aggregations of the sea urchin Strongylocentrotus droebachiensis drive the transition between alternative ecosystem states in Nova Scotia, from productive kelp beds to less productive barrens.

Cytoskeleton, EarlyView.ABSTRACT Post‐translational modifications (PTMs) to tubulin subunits in microtubule filaments are thought to comprise a component of the tubulin code that specifies microtubule functions in cell physiology and animal development. Acetylation of Lysine‐40 (K40) on α‐tubulin (αTub‐K40ac) and glutamylation of both α‐ and β‐tubulin are two tubulin PTMs of ...
