Enzymes as chaperones and chaperones as enzymes
FEBS Letters, 1998 Chaperones and foldases are two groups of accessory proteins which assist maturation of nascent peptides into functional proteins in cells. Protein disulfide isomerase, a foldase, and ATP‐dependent proteases, responsible for degradation of misfolded proteins in cells, both have intrinsic chaperone activities.

Direct Single Molecule Imaging of Enhanced Enzyme Diffusion [PDF]
Phys. Rev. Lett. 123, 128101 (2019), 2018 Recent experimental results have shown that active enzymes can diffuse faster when they are in the presence of their substrates. Fluorescence correlation spectroscopy (FCS), which relies on analyzing the fluctuations in fluorescence intensity signal to measure the diffusion coefficient of particles, has typically been employed in most of the prior ...

Analysis of nucleosome repositioning by yeast ISWI and Chd1 chromatin remodeling complexes [PDF]
, 2006 ISWI proteins form the catalytic core of a subset of ATP-dependent chromatin remodelling activities in eukaryotes from yeast to man. Many of these complexes have been found to reposition nucleosomes, but with different directionalities.

Integrative genomic mining for enzyme function to enable engineering of a non-natural biosynthetic pathway. [PDF]
, 2015 The ability to biosynthetically produce chemicals beyond what is commonly found in Nature requires the discovery of novel enzyme function. Here we utilize two approaches to discover enzymes that enable specific production of longer-chain (C5-C8) alcohols

Non-toxic total nitrogen determination using a low alkaline persulfate digestion
MethodsX, 2020 Measuring total nitrogen, nitrate, and nitrite is critical for compliance with water safety standards. Previous methods for measuring total nitrogen were hazardous, time consuming, and expensive.

Master curve of boosted diffusion for ten catalytic enzymes [PDF]
, 2020 Molecular agitation more rapid than thermal Brownian motion is reported for cellular environments, motor proteins, synthetic molecular motors, enzymes, and common chemical reactions, yet that chemical activity couples to molecular motion contrasts with generations of accumulated knowledge about diffusion at equilibrium. To test the limits of this idea,

Formation of Enzyme-Enzyme Heteroconjugates
Agricultural and Biological Chemistry, 1984 Enzyme-enzyme heteroconjugates of phosphoglyceromutase, enolase and pyruvate kinase, which sequentially act to produce ATP in the glycolytic pathway, were constructed with a bifunctional reagent, N-succinimidyl 3-(2-pyridyldithio)propionate. The conjugates of phospho-glyceromutase-enolase, enolase-pyruvate kinase and phosphoglyceromutase-enolase ...
