Nanofibrous membranes for single-step immobilization of hyperthermophilic enzymes

JOURNAL OF MEMBRANE SCIENCE, 472, 251–260.

By: C. Tang n, C. Saquing n, P. Sarin n, R. Kelly n & S. Khan n

author keywords: Enzyme immobilization; Nanofibers; Electrospinning; Chemical crosslinking; Hyperthermophilic enzymes
TL;DR: Analysis of this immobilization method indicates that the apparent decrease in specific activity could be attributed to enzyme deactivation arising from the crosslinking reaction, whereas mass transfer limits the apparent activity using alternative two-step immobilization methods.

Molecular Description of the LCST Behavior of an Elastin-Like Polypeptide

BIOMACROMOLECULES, 15(10), 3522–3530.

MeSH headings : Cold Temperature; Elastin / chemistry; Hydrophobic and Hydrophilic Interactions; Oligopeptides / chemistry; Peptides / chemistry; Protein Structure, Secondary; Solutions / chemistry; Solvents / chemistry; Transition Temperature; Water / chemistry
TL;DR: The results lead to propose that the LCST phase behavior of poly(VPGVG)18 is a collective phenomenon that originates from the correlated gradual changes in single polypeptide structure and the abrupt change in properties of hydration water around the peptide and is a result of a competition between peptide- peptide and peptides-water interactions.
