Molecular Characterization of the Cytidine Monophosphate-N-Acetylneuraminic Acid Hydroxylase (CMAH) Gene Associated with the Feline AB Blood Group System. [PDF]

open access: yesPLoS ONE, 2016
Cat's AB blood group system (blood types A, B, and AB) is of major importance in feline transfusion medicine. Type A and type B antigens are Neu5Gc and Neu5Ac, respectively, and the enzyme CMAH participating in the synthesis of Neu5Gc from Neu5Ac is ...

Production of α1,3-galactosyltransferase and cytidine monophosphate-N-acetylneuraminic acid hydroxylase gene double-deficient pigs by CRISPR/Cas9 and handmade cloning. [PDF]

open access: yesJ Reprod Dev, 2017
Gene-knockout pigs hold great promise as a solution to the shortage of organs from donor animals for xenotransplantation. Several groups have generated gene-knockout pigs via clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated 9 (Cas9) and somatic cell nuclear transfer (SCNT).

Cytidine monophosphate N-acetylneuraminic acid synthetase enhances invasion of human triple-negative breast cancer cells. [PDF]

open access: yesOnco Targets Ther, 2018
Cancer cells have altered bioenergetics, which contributes to their ability to proliferate, survive in unusual microenvironments, and invade other tissues. Changes in glucose metabolism can have pleomorphic effects on tumor cells.To investigate potential mechanisms responsible for the increased malignancy associated with altered glucose metabolism, we ...

Cytidine Monophosphate N-Acetylneuraminic Acid Synthetase and Solute Carrier Family 35 Member A1 Are Required for Reovirus Binding and Infection. [PDF]

open access: yesJ Virol, 2020
Attachment factors and receptors are important determinants of dissemination and tropism during reovirus-induced disease. In a CRISPR cell survival screen, we discovered two genes, Cmas and Slc35a1 , which encode proteins required for sialic acid ...

Hydroxylation of N-acetylneuraminic Acid Influences the in vivo Tropism of N-linked Sialic Acid-Binding Adeno-Associated Viruses AAV1, AAV5, and AAV6 [PDF]

open access: yesFrontiers in Medicine, 2021
Adeno-associated virus (AAV) vectors are promising candidates for gene therapy. However, a number of recent preclinical large animal studies failed to translate into the clinic. This illustrates the formidable challenge of choosing the animal models that

Purification, properties, and genetic location of Escherichia coli cytidine 5′-monophosphate N-acetylneuraminic acid synthetase.

open access: yesJournal of Biological Chemistry, 1987
N-Acetylneuraminic acid cytidylyltransferase (EC 2.7.7.43) (CMP-NeuAc synthetase) catalyzes the formation of cytidine monophosphate N-acetylneuraminic acid. We have purified CMP-NeuAc synthetase from an Escherichia coli O18:K1 cytoplasmic fraction to apparent homogeneity by ion exchange chromatography and affinity chromatography on CDP-ethanolamine ...

Covalent modification of lys19 in the ctp binding site of cytidine 5′‐monophosphate n‐acetylneuraminic acid synthetase [PDF]

open access: yesProtein Science, 1999
AbstractPeriodate oxidized CTP (oCTP) was used to investigate the importance of lysine residues in the CTP binding site of the cytidine 5′‐monophosphate N‐acetylneuraminic acid (CMP‐NeuAc) synthetase (EC 2.7.7.43) from Haemophilus ducreyi. The reaction of oCTP with the enzyme follows pseudo‐first‐order saturation kinetics, giving a maximum rate of ...

Mammalian cytidine 5′-monophosphate N -acetylneuraminic acid synthetase: A nuclear protein with evolutionarily conserved structural motifs [PDF]

open access: yesProceedings of the National Academy of Sciences, 1998
Sialic acids of cell surface glycoproteins and glycolipids play a pivotal role in the structure and function of animal tissues. The pattern of cell surface sialylation is species- and tissue-specific, is highly regulated during embryonic development, and changes with stages of differentiation. A prerequisite for the synthesis of sialylated

Regulation of colominic acid biosynthesis by temperature: Role of cytidine 5′‐monophosphate N‐acetylneuraminic acid synthetase [PDF]

open access: yesFEBS Letters, 1989
Synthesis of colominic acid in Escherichia coli K‐235 is strictly regulated by temperature. Evidence for the role of cytidine 5′‐monophospho‐N‐acetylneuraminic acid (CMP‐Neu5Ac) synthetase in this regulation was obtained by measuring its level in E. coli grown at 20 and 37°C. No activity was found in E. coli grown at 20°C.
