Motivated by the problem of domain formation in chromosomes, we studied a co--polymer model where only a subset of the monomers feel attractive interactions. These monomers are displaced randomly from a regularly-spaced pattern, thus introducing some quenched disorder in the system. Previous work ...

The peroxidase activity of cytochrome c is proposed to contribute to apoptosis by peroxidation of cardiolipin in the mitochondrial inner membrane. However, cytochrome c heme is hexa-coordinate with a methionine (Met80) on the distal side, stopping it from acting as an efficient peroxidase. The ...

Hydrogen-bonded organic frameworks (HOFs), a new type of porous material following the metal-organic frameworks (MOFs), covalent organic frameworks (COFs), etc., have emerged as one of the promising candidates in diverse potential applications. In this highlight, we summarize the key progress of ...

Recently we reported an Eley–Rideal/Mars–van Krevelen mechanism for ammonia synthesis on cobalt molybdenum nitride (Co3Mo3N). In this mechanism hydrogenation of activated dinitrogen occurs directly from the gas phase in a low barrier step forming a hydrazinylidene intermediate [[double bond, ...

Glyoxalase II (GlxII) is an antioxidant glutathione-dependent enzyme, which catalyzes the hydrolysis of S-D-lactoylglutathione to form D-lactic acid and glutathione (GSH). The last product is the most important thiol reducing agent present in all eukaryotic cells that have mitochondria and ...
