Enhanced saccharification levels of corn starch using as a strategy a novel amylolytic complex (AmyHb) from the thermophilic fungus var. in association with commercial enzyme.

Amylases represent a versatile group of catalysts that are used for the saccharification of starch because they can hydrolyze the glycosidic bonds of starch molecules to release glucose, maltose, and short-chain oligosaccharides. The amylolytic complex of the thermophilic filamentous fungus var (AmyHb) was produced, biochemically characterized, and compared with the commercial amylase Termamyl. In addition, the biotechnological application of AmyHb in starch saccharification was investigated.

Biochemical characterization, stability, and kinetics of three substrates of the recombinant TMPRSS2 serine protease domain.

Transmembrane serine protease 2 (TMPRSS2) is a membrane-bound protease belonging to the type II transmembrane serine protease (TTSP) family. It is a multidomain protein, including a serine protease domain responsible for its self-activation. The protein has been implicated as an oncogenic transcription factor and for its ability to cleave (prime) the SARS-CoV-2 spike protein.
