Two functionally distinctive phosphopantetheinyl transferases from amoeba Dictyostelium discoideum. [PDF]

open access: yesPLoS ONE, 2011
The life cycle of Dictyostelium discoideum is proposed to be regulated by expression of small metabolites. Genome sequencing studies have revealed a remarkable array of genes homologous to polyketide synthases (PKSs) that are known to synthesize ...

Regulation of Signal Transduction by Glutathione Transferases

open access: yesInternational Journal of Hepatology, 2012
Glutathione transferases (GST) are essentially known as enzymes that catalyse the conjugation of glutathione to various electrophilic compounds such as chemical carcinogens, environmental pollutants, and antitumor agents.

Enhanced Rishirilide Biosynthesis by a Rare In-Cluster Phosphopantetheinyl Transferase in Streptomyces xanthophaeus

open access: yesMicrobiology Spectrum, 2022
Phosphopantetheinyl transferases (PPTases) play important roles in activating apo-acyl carrier proteins (apo-ACPs) and apo-peptidyl carrier proteins (apo-PCPs) in both primary and secondary metabolism. PPTases catalyze the posttranslational modifications

Conserved sequence motifs in human TMTC1, TMTC2, TMTC3, and TMTC4, new O-mannosyltransferases from the GT-C/PMT clan, are rationalized as ligand binding sites

open access: yesBiology Direct, 2021
Background The human proteins TMTC1, TMTC2, TMTC3 and TMTC4 have been experimentally shown to be components of a new O-mannosylation pathway. Their own mannosyl-transferase activity has been suspected but their actual enzymatic potential has not been ...

The Ribosomal Peptidyl Transferase [PDF]

open access: yesMolecular Cell, 2007
Peptide bond formation on the ribosome takes place in an active site composed of RNA. Recent progress of structural, biochemical, and computational approaches has provided a fairly detailed picture of the catalytic mechanism of the reaction. The ribosome accelerates peptide bond formation by lowering the activation entropy of the reaction due to ...

Structure and functions of glutathione transferases

open access: yesThe Ukrainian Biochemical Journal, 2014
Data about classification, nomenclature, structure, substrate specificity and role of many glutathione transferase’s isoenzymes in cell functions have been summarised. The enzyme has been discovered more than 50 years ago.

The sigma-and omega-class members of the glutathione-S-transferase family from ascaris are IgE binding components with marked differences in the IgG1 and IgG4 response

open access: yesRevista Alergia México, 2018
Background: The family of gluthation-S-transferases possesses several isoforms, one of its members, Asc s 13, is allergenic, but other molecules of this repertoire may have different immunological properties.

Glutathione transferases in bacteria [PDF]

open access: yesThe FEBS Journal, 2008
Bacterial glutathione transferases (GSTs) are part of a superfamily of enzymes that play a key role in cellular detoxification. GSTs are widely distributed in prokaryotes and are grouped into several classes. Bacterial GSTs are implicated in a variety of distinct processes such as the biodegradation of xenobiotics, protection against chemical and ...
