PubMed ID22048246
'NAA10 gene encodes the catalytic subunit of N(alpha)-acetyltransferase NatA that catalyzes the acetylation of the N-termini of many eukaryotic proteins. A homologous gene called NAA11 is also present in mammalian cells. hNaa10p and hNaa11p are reported to be co-expressed in human cell cultures. In mouse tissues, however, Naa11 transcripts can ...

The plant biotin synthase reaction. Identification and characterization of essential mitochondrial accessory protein components.
AuthorsPicciocchi A, Douce R, Alban C,
JournalJ Biol Chem
PubMed ID12714594
In plants, the last step of the biotin biosynthetic pathway is localized in mitochondria. This chemically complex reaction is catalyzed by the biotin synthase protein, encoded by the bio2 gene in Arabidopsis thaliana. Unidentified mitochondrial proteins in addition to the bio2 gene product are obligatory for the reaction to occur. ... More
Construction and testing of engineered zinc-finger proteins for sequence-specific modification of mtDNA.

PubMed ID20134433
Engineered zinc-finger proteins (ZFPs) are hybrid proteins developed to direct various effector domains (EDs) of choice to predetermined DNA sequences. They are used to alter gene expression and to modify DNA in a sequence-specific manner in vivo and in vitro. Until now, ZFPs have mostly been used to target DNA ... More
Quantification of adenosine-to-inosine editing of microRNAs using a conventional method.
AuthorsKawahara Y
JournalNat Protoc
PubMed ID22743833
In this protocol, I describe a method for measuring the frequency of adenosine-to-inosine RNA editing of primary, precursor and mature forms of specific microRNAs (miRNAs) derived from the same source. The procedure involves reverse transcription (RT)-PCR amplification of regions containing the editing sites followed by subcloning of the PCR products ... More
Assembling the glycopeptide antibiotic scaffold: The biosynthesis of A47934 from Streptomyces toyocaensis NRRL15009.

The glycopeptide antibiotics vancomycin and teicoplanin are vital components of modern anti-infective chemotherapy exhibiting outstanding activity against Gram-positive pathogens including members of the genera Streptococcus, Staphylococcus, and Enterococcus. These antibiotics also provide fascinating examples of the chemical and associated biosynthetic complexity exploitable in the synthesis of natural products by actinomycetes ... More
Molecular cloning and characterization of human nonsteroidal anti-inflammatory drug-activated gene promoter. Basal transcription is mediated by Sp1 and Sp3.
Authors Baek S J; Horowitz J M; Eling T E;
JournalJ Biol Chem
PubMed ID11445565
Nonsteroidal anti-inflammatory drug-activated gene (NAG-1) is known to be associated with anti-tumorigenic activity and belongs to the transforming growth factor-beta superfamily. In the present study, we cloned the promoter region (-3500 to +41) and investigated the transcriptional regulatory mechanisms of the basal expression of the human NAG-1 gene. Several potential ...

Glycosylation of wall teichoic acid in Staphylococcus aureus by TarM.
AuthorsXia G, Maier L, Sanchez-Carballo P, Li M, Otto M, Holst O, Peschel A
JournalJ Biol Chem
PubMed ID20185825
Wall teichoic acid (WTA) glycopolymers are major constituents of cell envelopes in Staphylococcus aureus and related gram-positive bacteria with important roles in cell wall maintenance, susceptibility to antimicrobial molecules, biofilm formation, and host interaction. Most S. aureus strains express polyribitol phosphate WTA substituted with D-alanine and N-acetylglucosamine (GlcNAc). WTA sugar ... More
