The three-dimensional structure of the sulfhydryl protease calotropin DI from the madar plant, Calotropis gigantea, has been determined at 3.2 A resolution using the multiple isomorphous replacement method with five heavy atom derivatives. A Fourier synthesis based on protein phases with a mean
In the present study we compared the clot inducing and dissolving properties of Calotropis gigantea R. Br. (Asclepiadaceae), Synadenium grantii Hook. f. (Euphorbiaceae) and Wrightia tinctoria R. Br. (Apocynaceae) latex extracts. All the three latex extracts hydrolyzed casein, fibrinogen and crude
Procerain B is a novel cysteine protease isolated from Calotropis procera by our group and published recently. We have further characterized the enzyme by N-terminal sequencing and peptide mass fingerprinting. Procerain B showed maximum sequence similarity (80%) with Asclepain. Moreover, the
This article reports the characterization and evaluation of the biotechnological potential of a cysteine protease purified from Calotropis procera (CpCP3). This enzyme was highly stable to different metal ions and was able to hydrolyze κ-casein similarly to bovine chymosin. Atomic force microscopy
We have previously reported isolation and characterization of a novel plant cysteine protease, Procerain B, from the latex of Calotropis procera. Our initial attempts for active recombinant Procerain B in Escherichiacoli expression system was not successful. The reason for inactive enzyme production
BACKGROUND
Plant latex is a natural source of biologically active compounds and several hydrolytic enzymes responsible for their diverse health benefits. Recent past has witnessed substantial progress in understanding their supplementary industrial and pharmaceutical utility. Calotropis gigantea is
A protease was purified to homogeneity from the latex of medicinal plant Calotropis procera (Family-Asclepiadaceae). The molecular mass and isoelectric point of the enzyme are 28.8 kDa and 9.32, respectively. Hydrolysis of azoalbumin by the enzyme was optimal in the range of pH 7.0-9.0 and
Calotropis procera R. Br., a traditional medicinal plant in India, is a promising source of commercial proteases, because the cysteine proteases from the plant exhibit high thermo-stability, broad pH optima, and plasma-clotting activity. Though several proteases such as Procerain, Procerain B,
Hemostasis is a tightly regulated process which maintains a fluid state of blood within the vasculature and provides thrombotic response upon tissue injury. Various scientific studies have implicated the role of plant latex proteases in hemostasis using in vitro experiments. However, in vivo models
In the present study we evaluated the presence of cysteine protease from the latex of four plants Asclepias curassavica L., Calotropis gigantea R.Br., Pergularia extensa R.Br. and Cynanchum puciflorum R.Br. belongs to the family Asclepiadaceae. Cysteine proteases from these plants latex exhibited
Objective and design: Oral mucositis (OM) is an intense inflammatory reaction progressing to tissue damage and ulceration. The medicinal uses of Calotropis procera are supported by anti-inflammatory capacity. PII-IAA, a highly homogenous cocktail of laticifer
Soluble proteins from the latex of Calotropis procera (LP) were investigated in vitro and in vivo for digestibility as the latex has previously been shown to produce considerable toxic effects on animals. The latex is also an important biologically active compound that displays antiinflammatory and
The structural and functional aspects along with equilibrium unfolding of procerain, a cysteine protease from Calotropis procera, were studied in solution. The energetic parameters and conformational stability of procerain in different states were also estimated and interpreted. Procerain belongs to
Procerain B, a novel cysteine protease (endopeptidase) isolated from Calotropis procera belongs to Asclepiadaceae family. Purification of the enzyme, biochemical characterization and potential applications are already published by our group. Here, we report cDNA cloning, complete amino acid
