Cystatins
WebPlant cystatins have special characteristics which permit them to be classified in a special class called Phytocystatin. One is the presence of a N-terminal alpha-helix, present only in plant cystatins. Phytocystatins are involved in several process, including plant germination and defense. van Wyk et al. found some 19 different cystatins ... WebMay 1, 2008 · The cystatins are tight binding and reversible inhibitors. The basic mechanism of interaction between cystatins and their target proteases has been established, based mainly on the crystal structures of various cathepsins, stefins and cystatins and their enzyme-inhibitor complexes. Cystatins, as rather non-selective …

WebType 1 cystatin contains small polypeptides with a lack of the carbohydrate side-chains and disulfide bridges found in other cystatins . Type 2 cystatin is a secretory protein that contains signal peptides; secretory cystatin helps the tick to evade the host’s immune system by processing the antigen-presenting cells (APCs) of the host. WebNov 1, 2024 · Cystatins are endogenous, tight-binding and reversible inhibitors of the C1 and C13 families of cysteine peptidases, that are present in tissues and biological fluids [ [1], [2], [3] ]. The primary role of cystatins is to limit excessive activity of cysteine peptidases.

WebCystatin C is a non- glycosylated, basic protein ( isoelectric point at pH 9.3). The crystal structure of cystatin C is characterized by a short alpha helix and a long alpha helix which lies across a large antiparallel, five- stranded beta sheet.
