The preparation and characterisation of novel microperoxidase biocatalysts [PDF]

, 1987
Microperoxidases are haem oligopeptides, derived from the proteolytic digestion of cytochrome c, possessing peroxidase activity. They are termed "microperoxidases" in contrast to other relatively large peroxidases such as horseradish peroxidase.

Halogenation Activity of Mammalian Heme Peroxidases

, 2023
Mammalian heme peroxidases are fascinating due to their unique peculiarity of oxidizing (pseudo)halides under physiologically relevant conditions. These proteins are able either to incorporate oxidized halides into substrates adjacent to the active site ...

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

FEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

Two cationic peroxidases from cell walls of Araucaria araucana seeds [PDF]

, 1995
We have previously reported the purification and partial characterization of two cationic peroxidases from the cell walls of seeds and seedlings of the South American conifer, Araucaria araucana. In this work, we have studied the amino acid composition

Rab14 regulates the transport of human papillomavirus to the trans‐Golgi network for infectious cell entry

FEBS Letters, EarlyView.
This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.

Production of Ligninolytic Enzymes by Coptotermes curvignathus Gut Bacteria

Environmental and Climate Technologies, 2019
Maximum utilization of lignocellulosic biomass is contingent upon degrading the recalcitrant lignin polymer. Conventional methods employed in delignification require high inputs of energy and chemicals, resulting in the release of highly toxic effluents.

Electrochemical Conversion of the Lignin Model Veratryl Alcohol to Veratryl Aldehyde Using Manganese(III)-Schiff Base Homogeneous Catalysts

Applied Sciences, 2019
Lignin and other colored structures need to be bleached after the Kraft process in the pulp industry. Development of environmentally-safe bleaching catalysts or electrocatalysts constitutes an attractive strategy for selective removal of lignin.

The role of miR‐335‐5p in the redifferentiation of BRAF p.V600E thyroid cancers

Molecular Oncology, EarlyView.
The BRAF p.V600E mutation promotes thyroid cancer dedifferentiation and radioiodine resistance. Using a network approach, we identified miR‐335‐5p as a key regulator of BRAF‐mutated thyroid tumors. Restoring miR‐335‐5p increased thyroid‐specific gene expression and iodine uptake in cells and organoids.

Ligninolytic enzyme potential of Trametes spp. associated with leaf litter in riparian forest of the Amazônia region [PDF]

Brazilian Journal of Biology
The present study explored the potential of leaf litter as a source of fungi able to produce ligninolytic enzymes for the biodegradation of anthraquinone dyes. Within the colonies isolated from the leaf litter, only three colonies of two species Trametes

Leishmania major Peroxidase Is a Cytochrome c Peroxidase [PDF]

Biochemistry, 2012
Leishmania major peroxidase (LmP) exhibits both ascorbate and cytochrome c peroxidase activities. Our previous results illustrated that LmP has a much higher activity against horse heart cytochrome c than ascorbate, suggesting that cytochrome c may be the biologically important substrate.
