Subtilisin
Subtilisin is a protease (a protein-digesting enzyme) initially obtained from Bacillus subtilis. Subtilisins belong to subtilases, a group of serine proteases that – lik
Proprotein convertases (PPCs) are a family of proteins that activate other proteins
Many proteins are inactive when they are first synthesized, because they contain chains of amino acids that block their activity. Proprotein convertases remove those chains and act
Structure of DNA repair protein XRCC4 aka X-ray repair cross-complementing protein 4
XRCC4 protein is a TETRAMER that resembles the shape of a DUMBBELL containing two globular ends separated by a long, thin stalk. The tetramer is composed of two dimers, and each
