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.

Mitochondrial DNA replication in sea urchin oocytes [PDF]
, 1974 Mitochondrial DNA (mtDNA) replicative intermediates from Strongylocentrotus purpuratus oocytes were isolated by ethidium bromide-CsCl density gradient centrifugation and examined by electron microscopy after formamide spreading.

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 ...

Two-step growth mechanism of supported Co3O4-based sea-urchin like hierarchical nanostructures [PDF]
, 2018 The formation mechanism of Co3O4-based sea-urchin like nanostructures from Co-O-B layers is unveiled. In this process, promoted by oxidizing annealing, B plays a major role, inducing first a chemical reduction of Co and the formation of a metallic ...

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 ...

Developmental Dynamics, EarlyView.Abstract Background The emergence of multicellularity in animals marks a pivotal evolutionary event, which was likely enabled by molecular innovations in the way cells adhere and communicate with one another. β‐Catenin is significant to this transition due to its dual role as both a structural component in the cadherin–catenin complex and as a ...

The California Red Sea Urchin, Strongylocentrotus franciscanus, Fishery: Catch, Effort, and Management Trends [PDF]
, 1997 California's red sea urchin, Strongylocentrotus franciscanus, catch peaked at 23,577 metric tons (t) in 1988. Since then, catches and CPUE have trended downward at different rates in northern and southern California, with 10,086 t landed statewide in ...

Developmental Dynamics, EarlyView.Abstract Background Biomineralization is a vital biological process through which organisms produce mineralized structures such as shells, skeletons, and teeth. Microtubules are essential for biomineralization in various eukaryotic species; however, their specific roles in this process remain unclear.
