O-sulfonation of serine and threonine: mass spectrometric detection and characterization of a new posttranslational modification in diverse proteins throughout the eukaryotes.
Protein sulfonation on serine and threonine residues is described for the first time. This post-translational modification is shown to occur in proteins isolated from organisms representing a broad span of eukaryote evolution, including the invertebrate mollusk Lymnaea stagnalis, the unicellular malaria parasite Plasmodium falciparum, and humans. Detection and structural characterization of thi...

1 (1-1) and inhibitor-2 (1-2), and preferentially dephosphorylate the /3-subunit of phosphorylase kinase, whereas type-2 phosphatases are insensitive to the heat-stable inhibitors and preferentially dephosphorylate the x-subunit of phosphorylase kinase [1,2]. Type-2 phosphatases can be further subdivided into spontaneously active (PP2A), Ca2l-dependent (PP2B) and Mg2+dependent (PP2C) classes. T...

rides consisting of six or more cr-1,4-linked Dglucopyranose units which possess primary hydroxyl groups at the C-6 positions and secondary hydroxyl groups at the C-2 and C-3 positions. Because cyclomaltooligosaccharides have a hydrophobic and optically active interior, they have been utilized as transporters of hydrophobic molecules and as small molecular mimics of enzymes. One of the cyclomal...
متن کاملSerine/Threonine Response Elements
T RANSCRIPTION in eukaryotes involves transcriptional activators, proteins that bind to specific sites distal from the TATA box termed enhancers or u p stream activation sequences (UASs) . When bound to a UAS, a transcriptional activator is able to stimulate the transcription initiation complex leading to synthesis of the mRNA. The ability of Saccharomyces cermisiar to use serine or threonine a...
متن کاملCharacterization of a Hank's type serine/threonine kinase and serine/threonine phosphoprotein phosphatase in Pseudomonas aeruginosa.
Pseudomonas aeruginosa is an opportunistic pathogen that causes infections in eye, urinary tract, burn, and immunocompromised patients. We have cloned and characterized a serine/threonine (Ser/Thr) kinase and its cognate phosphoprotein phosphatase. By using oligonucleotides from the conserved regions of Ser/Thr kinases of mycobacteria, an 800-bp probe was used to screen P. aeruginosa PAO1 genom...
