چکیده

Abstract Chitin is abundant in nature and its degradation products are highly valuable for numerous applications. Thermophilic chitinases increasingly appreciated their capacity to biodegrade chitin at high temperatures prolonged enzyme stability. Here, using deep learning approaches, we developed a prediction tool, Preoptem, screen thermophilic proteins. A novel chitinase, Chi304, was mined directly from the marine metagenome. Chi304 showed maximum activity 85 ℃, T m reached 89.65 ± 0.22℃, exhibited excellent thermal stability 80 90 °C. had both endo- exo-chitinase activities, (GlcNAc) 2 main hydrolysis product of chitin-related substrates. The yields colloidal 97% within min, 20% over 4 days reaction with crude powder. This study thus provides method mine chitinase efficient biodegradation. Graphical

Identification of novel non-metal haloperoxidases from the marine metagenome.

Haloperoxidase (HPO, E.C.1.11.1.7) is a metal-containing enzyme oxidizing halonium species, which can be used in the synthesis of halogenated organic compounds, for instance in the production of antimicrobial agents, cosmetics, etc., in the presence of halides and H2O2. To isolate and evaluate a novel non-metal HPO using a culture-independent method, a cassette PCR library was constructed from ...

A novel chitinase inhibitor from a marine bacterium, Pseudomonas sp.

A new chitinase inhibitor, CI-4, was isolated from the culture broth of a marine bacterium Pseudomonas sp. IZ208. The structure of CI-4 was determined to be cyclo(L-Arg-D-Pro) by spectral studies and comparison with a synthetic sample. CI-4 showed inhibitory activity against chitinase.
