The pointed $p$-groups on a block algebra [PDF]
arXiv, 2023 A pointed $p$-group is a pointed group $P_\gamma$ such that $P$ is a $p$-group. We parameterize the pointed $p$-groups on a group algebra or on a block algebra of a group algebra. The parameterization involves $p$-subgroups and irreducible characters of centralizers of $p$-subgroups.

BMC Cell Biology, 2009 Background Parathyroid hormone (PTH) gene expression is regulated post-transcriptionally through the binding of the trans-acting proteins AU rich binding factor 1 (AUF1), Upstream of N-ras (Unr) and KH-type splicing regulatory protein (KSRP) to an AU ...

Multiple RNA processing defects and impaired chloroplast function in plants deficient in the organellar protein-only RNase P enzyme. [PDF]
PLoS ONE, 2015 Transfer RNA (tRNA) precursors undergo endoribonucleolytic processing of their 5' and 3' ends. 5' cleavage of the precursor transcript is performed by ribonuclease P (RNase P).

The Multiple Substrate Recognition Properties of Ribonuclease P [PDF]
Biophysical Journal, 2012 Ribonuclease P is an essential enzyme that is responsible for catalyzing the 5’end maturation of transfer RNA. In Bacteria, the RNase P holoenzyme is composed of a large RNA (∼400nt) and a smaller (∼100aa) protein. RNase P RNA contains the enzyme active site and interacts with tRNA; however, the protein subunit is essential in vivo because it binds the

Assessing site-specific enhancements imparted by hyperpolarized water in folded and unfolded proteins by 2D HMQC NMR [PDF]
arXiv, 2020 Hyperpolarized water can be a valuable aid in protein NMR, leading to amide group 1H polarizations that are orders of magnitude larger than their thermal counterparts. Suitable procedures can exploit this to deliver 2D 1H-15N correlations with good resolution and enhanced sensitivity.

Tertiary structure prediction of C-peptide of ribonuclease A by multicanonical algorithm [PDF]
J. Phys. Chem. B 102 (1998) 653-656, 1998 We have performed multicanonical Monte Carlo simulations of C-peptide of ribonuclease A. It is known by CD and NMR experiments that this peptide has high alpha-helix content in aqueous solution and that the side-chain charges of residues Glu-2$^-$ and His-12$^+$ play an important role in the stability of the alpha-helix.

Transcriptional control of an essential ribozyme in Drosophila reveals an ancient evolutionary divide in animals. [PDF]
PLoS Genetics, 2015 Ribonuclease P (RNase P) is an essential enzyme required for 5'-maturation of tRNA. While an RNA-free, protein-based form of RNase P exists in eukaryotes, the ribonucleoprotein (RNP) form is found in all domains of life.

Antibodies in human serum that precipitate ribonuclease P. [PDF]
Proceedings of the National Academy of Sciences, 1988 Sera from certain patients with systemic lupus erythematosus (SLE) and related rheumatic diseases contain antibodies that selectively deplete extracts of HeLa cells of RNase P activity. Most of the sera that recognize RNase P, an endoribonuclease with an essential RNA subunit, also contain antibodies against another small ribonucleoprotein known as the

On nonhyperbolicity of P/P and P/SF knots in $S^3$ [PDF]
arXiv, 2020 In [B90] or an available version [B18], Berge constructed twelve families of primitive/primitve(or simply P/P) knots, which are referred to as the Berge knots. It is proved in [B08] or independently in [G13] that all P/P knots are the Berge knots, which gives the complete classification of P/P knots.
