The preparation and characterisation of novel microperoxidase biocatalysts [PDF]

open access: yes, 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.

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

open access: yesFEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

Preparation and Enzymic Hydrolysis of Riboflavin Diesters

open access: yesTHE JOURNAL OF VITAMINOLOGY, 1969
Riboflavin-2′, 3′-dibenzoate, riboflavin-4′, 5′-dibenzoate, riboflavin-2′, 3′-di-n-butyrate, riboflavin-4′, 5′-di-n-butyrate, riboflavin-2′, 3′-dinicotinate and riboflavin-4′, 5′-dinicotinate were prepared from the monoisopropylidene derivatives. Migration of acyl group was observed in the riboflavin-2′, 3′-diesters.

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

open access: yesFEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Enzyme activity and dynamics in near-anhydrous conditions

open access: yes, 2009
Water is widely assumed to be essential for life 1, although the exact molecular basis of this requirement is unclear 2-4. Water facilitates protein motions 5-9 and although enzyme activity has been demonstrated at low hydrations in organic solvents 10 ...

Characterisation and effects of a xylanase enzyme preparation extracted from Thermomyces lanuginosus cultures [PDF]

open access: yes, 2001
This paper describes the production of an enzyme preparation from the fungus Thermomyces lanuginosus. Thermal resistance, pH stability and lignocellulolytic activity of the enzyme preparation high in xylanase were studied on a variety of grains and ...
