Chromogenic detection of aminoglycoside phosphotransferases.

Methods in molecular medicine

Amoroso AM, Gutkind GO.
PMID: 21374411
Methods Mol Med. 2001;48:113-7. doi: 10.1385/1-59259-077-2:113.

Acquired resistance to aminoglycosides is most frequently due to the presence of the so-called aminoglycoside modifying enzymes (AGME) (1) able to catalyze one or more of three general reactions: N-acetylation, O-nucleotidylation and O-phosphorylation (2). Although resistance phenotype (to different...

Acid phosphatase/phosphotransferases from enteric bacteria.

Journal of bioscience and bioengineering

Mihara Y, Utagawa T, Yamada H, Asano Y.
PMID: 16233057
J Biosci Bioeng. 2001;92(1):50-4. doi: 10.1263/jbb.92.50.

We have investigated the enzymatic phosphorylation of nucleosides and found that Morganella morganii phoC acid phosphatase exhibits regioselective pyrophosphate (PP(i))-nucleoside phosphotransferase activity. In this study, we isolated genes encoding an acid phosphatase with regioselective phosphotransferase activity (AP/PTase) from Providencia...

Merestinib monotherapy or in combination for japanese patients with advanced and/or metastatic cancer: A phase 1 study.

This phase 1, multi-center, nonrandomized, open-label, dose-escalation study consisted of Part A wherein merestinib 80 or 120 mg (40-mg tablets) was administered orally QD during a 28-day cycle to patients diagnosed with solid tumors and Part B wherein merestinib...

Overview of protein phosphorylation in bacteria with a main focus on unusual protein kinases in Bacillus subtilis.

Research in microbiology

Zhang A, Pompeo F, Galinier A.
PMID: 34500011
Res Microbiol. 2021 Nov-Dec;172(7):103871. doi: 10.1016/j.resmic.2021.103871. Epub 2021 Sep 06.

Protein phosphorylation is a post-translational modification that affects protein activity through the addition of a phosphate moiety by protein kinases or phosphotransferases. It occurs in all life forms. In addition to Hanks kinases found also in eukaryotes, bacteria encode...

Differential contributions of choline phosphotransferases CPT1 and CEPT1 to the biosynthesis of choline phospholipids.

Journal of lipid research

Horibata Y, Sugimoto H.
PMID: 34331935
J Lipid Res. 2021;62:100100. doi: 10.1016/j.jlr.2021.100100. Epub 2021 Jul 29.

Choline phospholipids (PLs) such as phosphatidylcholine (PC) and 1-alkyl-2-acyl-sn-glycerophosphocholine are important components for cell membranes and also serve as a source of several lipid mediators. These lipids are biosynthesized in mammals in the final step of the CDP-choline pathway...

Comparison of the Activities and Some Properties of Pyrophosphate and ATP Dependent Fructose-6-Phosphate 1-Phosphotransferases of Phaseolus vulgaris Seeds.

Plant physiology

Botha FC, Small JG.
PMID: 16665337
Plant Physiol. 1987 Apr;83(4):772-7. doi: 10.1104/pp.83.4.772.

THE DISTRIBUTION OF PYROPHOSPHATE: fructose 6-phosphate phosphotransferase (PFP) and ATP: fructose-6-phosphate 1-phosphotransferase (PFK) was studied in germinating bean (Phaseolus vulgaris cv Top Crop) seeds. In the cotyledons the PFP activity was comparable with that of PFK. However, in the...

Singular features of trypanosomatids' phosphotransferases involved in cell energy management.

Enzyme research

Pereira CA, Bouvier LA, Cámara Mde L, Miranda MR.
PMID: 21603267
Enzyme Res. 2011;2011:576483. doi: 10.4061/2011/576483. Epub 2011 Apr 04.

Trypanosomatids are responsible for economically important veterinary affections and severe human diseases. In Africa, Trypanosoma brucei causes sleeping sickness or African trypanosomiasis, while in America, Trypanosoma cruzi is the etiological agent of Chagas disease. These parasites have complex life...

Modifying enzymes related aminoglycoside: analyses of resistant Acinetobacter isolates.

International journal of clinical and experimental medicine

Atasoy AR, Ciftci IH, Petek M.
PMID: 25932248
Int J Clin Exp Med. 2015 Feb 15;8(2):2874-80. eCollection 2015.

Enzymatic modification of aminoglycosides by nucleotidyltransferases, acetyltransferases and/or phosphotransferases accounts for the majority of aminoglycoside-resistant Acinetobacter isolates. In this study, we investigated the relationship between aminoglycoside resistance and the presence of aminoglycoside-modifying enzymes in Acinetobacter baumannii clinical isolate groups...

Look and Outlook on Enzyme-Mediated Macrolide Resistance.

Frontiers in microbiology

Golkar T, Zieliński M, Berghuis AM.
