Activity of Recombinant α and β Subunits of Casein Kinase II from Xenopus laevis
(1993)
Casein kinase II (CKII) is a ubiquitous protein kinase, found predominantly in cell nuclei, which has two subunits in a tetrameric α2β2 or αα′2 conformation. The catalytic center is present in the α subunit which is active ...
Identification and Characterization of an Alternatively Spliced Isoform of the Human Protein Phosphatase 2A alpha Catalytic Subunit
(Amer Soc Biochemistry Molecular Biology IncBethesdaEUA, 2012)
Identification of the acinetobacter baumannii ribonuclease p catalytic subunit: Cleavage of a target mRNA in the presence of an external guide sequence
(Frontiers Research Foundation, 2018-10)
The bacterial ribonuclease P or RNase P holoenzyme is usually composed of a catalytic RNA subunit, M1, and a cofactor protein, C5. This enzyme was first identified for its role in maturation of tRNAs by endonucleolytic ...
Chemical modification of SH groups of E. coli Phosphofructokinase-2 induces subunit dissociation: Monomers are inactive but preserve ligand binding properties
(Taylor & Francis, 2000)
Modification of Escherichia coli phosphofructokinase-2 (Pfk-2) with N- (1-pyrenil)maleimide results in an enzyme form that is inactive. However, the rate of modification is drastically reduced in the presence of the ...
Multiple isoforms for the catalytic subunit of PKA in the basal fungal lineage Mucor circinelloides
(Elsevier, 2016-12)
Protein kinase A (PKA) activity is involved in dimorphism of the basal fungal lineage Mucor. From the recently sequenced genome of Mucor circinelloides we could predict ten catalytic subunits of PKA. From sequence alignment ...
Neuroprotective effects of the catalytic subunit of telomerase : A potential therapeutic target in the central nervous system
(2016-07-01)
Senescence plays an important role in neurodegenerative diseases and involves key molecular changes induced by several mechanisms such as oxidative stress, telomere shortening and DNA damage. Potential therapeutic strategies ...
Role of the carboxyl terminus on the catalytic activity of protein kinase CK2α subunit
(2002)
Protein kinase CK2 (also known as casein kinase 2) has catalytic (α, α′) and regulatory (β) subunits. The role of carboxyl amino acids in positions from 324 to 328 was studied for Xenopus laevis CK2α. Deletions and mutations ...
The association of Na,K-ATPase subunits studied by circular dichroism, surface tension and dilatational elasticity
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2008)
Different stoichiometries are observed between alpha and beta subunits of Na,K-ATPase that depend on the method employed to solubilize and purify the enzyme. It is not known whether this variability is due to loss of ...
