The Ecballium elaterium trypsin inhibitor II (EETI-II) belongs to the family of squash inhibitors and is one of the strongest inhibitors known for trypsin. The eight independent molecules of EETI-II in the crystal structure reported here provide a good opportunity to test the hypothesis that this small cystine-knot protein (knottin) is sufficiently rigid to be used as a molecular scaffold for protein-engineering purposes. To extend this test, the structures of two complexes of EETI-II with trypsin have also been determined, one carrying a four-amino-acid mutation of EETI-II. The remarkable similarity of these structures confirms the rigidity of the molecular framework and hence its suitability as a molecular scaffold.

Antibody-based products constitute one of the most attractive biological molecules for diagnostic, medical imagery and therapeutic purposes with very few side effects. Their development has be- come a major priority of biotech and pharmaceutical industries. Recently, a growing number of modified antibody-based products have emerged including fragments, multi-specific and conjugate antibodies. In this study, using protein engineering, we have functionalized the anti-hen egg-white lysozyme (HEWL) camelid VHH antibody fragment (cAb-Lys3), by insertion into a solvent-exposed loop of the Bacillus licheniformis β-lactamase BlaP. We showed that the generated hybrid protein conserved its enzymatic activity while the ...

Mathematically, knots are only truly defined in loops, as a knot in an open string can just be slid off the end. Knots are loosely categorized by the minimum number of times the loop crosses over itself in a diagram (see below). The simplest knot, the trefoil, when drawn must cross itself a minimum of three times. For a given crossing number, there can be multiple kinds of knots. The two simplest knots, with three and four crossings, only have one type, then there are two for five, three for six, seven for seven, then it starts to explode: 165 for ten crossings, 9988 for thirteen, and over a million for sixteen. Beyond this, it is unknown how many kinds of knots there are (although there are constraints). Each type of knot has certain parameters that are unique to the knot, called invariants, and calculating these invariants is how knots can be distinguished. When dealing with knots in real ropes and polymers and DNA, we have to remember that it doesnt count as a knot unless the ends are ...

Generally found on twigs, branches and fruit spurs. Trunks can also be infected. infections usually start on young tissue. abnormal growth starts as light brown swellings that later enlarge, rupture and become black. During the second year, the growth continues to elongate along the branch and encircles it. Several knots may merge to make a large knot. In the second year the fungus in the knot dies except at the margins. The black knot is then invaded by secondary fungi that may change the color to a whitish or pinkish color. Insects frequently colonize older galls. With time and the spread of the disease, the tree loses vigor and dies. ...

The inhibitor cystine knot (ICK) is an unusual three-disulfide architecture in which one of the disulfide bonds bisects a loop formed by the two other disulfide bridges and the intervening sections of the protein backbone. Peptides containing an ICK motif are frequently considered to have high levels of thermal, chemical and enzymatic stability due to cross-bracing provided by the disulfide bonds. Experimental studies supporting this contention are rare, in particular for spider-venom toxins, which represent the largest diversity of ICK peptides. We used ω-hexatoxin-Hv1a (Hv1a), an insecticidal toxin from the deadly Australian funnel-web spider, as a model system to examine the contribution of the cystine knot to the stability of ICK peptides. We show that Hv1a is highly stable when subjected to temperatures up to 75 °C, pH values as low as 1, and various organic solvents. Moreover, Hv1a was highly resistant to digestion by proteinase K and when incubated in insect hemolymph and human plasma. We

In 1899, C. N. Little published a table of 43 nonalternating knots of 10 crossings that listed these two knots as being distinct. Seventy-five years later, Kenneth Perko, a lawyer and part-time mathematician, discovered that these were actually the same knot[1]. To say that two knots are the same is to say that one can be deformed into the other without breaking the knot or passing it through itself. To prove that two knots are the same, we can create one of them out of actual rope, and tug at it and move it around until it looks like the other. As the story goes, thats how Perko figured out that these knots are the same - by working with rope on his floor. We can also prove that two knots are the same by working with their projections. A projection of a knot is a flat representation of it, essentially a 2D drawing of the knot.

Cyclotides are considered promising scaffolds for drug development owing to their inherent host defence activities and highly stable structure, defined by the cyclic cystine knot. These proteins are expressed as complex mixtures in plants. Although several methods have been developed for their isolation and analysis, purification of cyclotides is still a lengthy process. Here, we describe the use of affinity chromatography for the purification of cyclotides using polyclonal IgG antibodies raised in rabbits against cycloviolacin O2 and immobilized on NHS-activated Sepharose columns. Cycloviolacin O2 was used as a model substance to evaluate the chromatographic principle, first as a pure compound and then in combination with other cyclotides, that is, bracelet cyclotide cycloviolacin O19 and Mobius cyclotide kalata B1, and in a plant extract. We demonstrate that single-step purification of cyclotides by affinity chromatography is possible but cross reactivity may occur between homologue cyclotides ...

The cyclotides are a family of naturally occurring peptides characterized by cyclic cystine knot (CCK) structural motif, which comprises a cyclic head-to-tail backbone featuring six conserved cysteine residues that form three disulfide bonds. This unique structural motif makes cyclotides exceptionally resistant to chemical, thermal and enzymatic degradation. They also exhibit a wide range of biological activities including insecticidal, cytotoxic, anti-HIV and antimicrobial effects.. The cyclotides found in plants exhibit considerable sequence and structural diversity, which can be linked to their evolutionary history and that of their host plants. To clarify the evolutionary link between sequence diversity and the distribution of individual cyclotides across the genus Viola, selected known cyclotides were classified using signature sequences within their precursor proteins. By mapping the classified sequences onto the phylogenetic system of Viola, we traced the flow of cyclotide genes over ...

Cyclotides are plant peptides comprising a circular backbone and three conserved disulfide bonds that confer them with exceptional stability. They were originally discovered in Oldenlandia affinis based on their use in traditional African medicine to accelerate labor. Recently, cyclotides have been identified in numerous plant species of the coffee, violet, cucurbit, pea, potato, and grass families. Their unique structural topology, high stability, and tolerance to sequence variation make them promising templates for the development of peptide-based pharmaceuticals. However, the mechanisms underlying their biological activities remain largely unknown; specifically, a receptor for a native cyclotide has not been reported hitherto. Using bioactivity-guided fractionation of an herbal peptide extract known to indigenous healers as "kalata-kalata," the cyclotide kalata B7 was found to induce strong contractility on human uterine smooth muscle cells. Radioligand displacement and second ...

Perhaps one of the most interesting aspects of the melanocortin system is that it has two endogenous antagonists, agouti and AGRP. These proteins are unique in that no inhibitory proteins have been identified for any of the seven-transmembrane receptor family. Agouti and AGRP are paracrine signaling molecules, which are endogenous antagonists of the MCRs (13). Of physiological significance, agouti and AGRP have MCR subtype selectivity (Table 1). Interestingly, agouti and AGRP both have a cysteine-rich COOH-terminal domain. Although the structure of agouti has not been resolved, nuclear magnetic resonance studies demonstrate that the cysteine residues in AGRP adopt a structural motif called an inhibitor cystine knot (32). This motif is common to invertebrate toxins, but in mammals this structure is unique to AGRP and, presumably, agouti. Another commonality is that agouti and AGRP have both been shown in vitro to be inverse agonists (33). Thus they have the potential in vivo to regulate their ...

Scientific work on knots can be roughly divided into three major categories: mathematical study of knot topology, rod-based models for physical knots, and experimental investigations of surgical suture knots. The first category pertains to mathematical knot theory where invariants for knots are sought and studied (see [5,6] and references therein). The studies in this field allow one to classify and distinguish types of knots and determine invariants of a particular knot topology (such as trefoil (or simple) knots, cinquefoil (or double) knots, and figure eight knots) that cannot be changed without cutting the strands of the knot. In the second category, studies in the mechanics of physical knots seek to use an elastic rod model to determine the deformation of the strands of a knot [7,8]. Owing to the interest in simulating and animating strands of hair, ropes and sutures in computer graphics, progress in this area has been rapid in the past decade (cf. [4,9]). However, simulating the dynamics ...

The online tutorial will last for 6 weeks with a video uploaded for each week. The videos will provide an in-depth teaching of Korean knot-making on some 3 basic Korean knots namely: Beondegi knot (Pupa knot), Dongsimgyul knot (Lovers knot), Dangcho knot (Creeper knot). In the course of 6 weeks, participants will be able to learn how to use Korean knots to make necklaces, bracelets, create name tags, amongst others, he said. He continued, the Korean knot is a traditional Korean handicraft which is made using one or more threads. Korean knots have unique braiding technique and are tied without the use of tools. In the past, knots were used to carry tools for hunting, communication and records or as a symbol of social status. But later, it became a form of art employed in ornamental creations. There are more than 30 basic types of Korean knots as well as many variations of the basic types. ...

The structures of transforming growth factor-β (TGF-β), nerve growth factor (NGF), platelet-derived growth factor (PDGF) and gonadotropin have been shown to be similar [1,2 and references therein]: these proteins are folded into two highly twisted antiparallel pairs of β-strands and contain three disulfide bonds, of which two form a cystine ring through which the third bond passes (see the schematic representation below). This structure is called cystine knot [3]. ...

I have been doing experiments stretching knotted DNA molecules in extensional fields**. I was trying to see how the knots behave at different levels of tension, so Id start by stretching them a lot then lowering the field systematically. Eventually, I get to the point where the molecule stops stretching. Something I noticed, however, was that if the knots were big enough, the molecule would collapse sooner, at a higher tension than expected for a molecule without a knot. This suggested that the knot was modifying the coil-stretch transition.. To investigate this, my colleague Vivek Narsimhan, who is now a professor at Purdue, ran a series of computer simulations of knotted polymer chains. The simulations involve having a chain of connected beads that have short-range repulsive interactions between the beads that prevent them from passing through each other. Each bead is subject to Newtons laws of motion, a drag force that depends on its velocity, as well as a random force that mimics thermal ...

In comparing the diagrams of knots of various strengths, the researchers were able to identify general “counting rules,†or characteristics that determine a knot’s stability. Basically, a knot is stronger if it has more strand crossings, as well as more “twist fluctuations††changes in the direction of rotation from one strand segment to another. For instance, if a fiber segment is rotated to the left at one crossing and rotated to the right at a neighboring crossing as a knot is pulled tight, this creates a twist fluctuation and thus opposing friction, which adds stability to a knot. If, however, the segment is rotated in the same direction at two neighboring crossing, there is no twist fluctuation, and the strand is more likely to rotate and slip, producing a weaker knot. They also found that a knot can be made stronger if it has more “circulations,†which they define as a region in a knot where two parallel strands loop against each other in opposite ...

Cyclotides are plant derived, cystine-knot stabilized peptides characterized by their natural abundance, sequence variability and structural plasticity. They are abundantly expressed in Rubiaceae, Psychotrieae in particular. Previously the cyclotide kalata B7 was identified to modulate the human oxytocin and vasopressin G protein-coupled receptors (GPCRs), providing molecular validation of the plants uterotonic properties and further establishing cyclotides as valuable sources for novel GPCR ligand design. In this study we screened a cyclotide extract derived from the root powder of the South American medicinal plant ipecac (Carapichea ipecacuanha) for its GPCR modulating activity of the corticotropin-releasing factor type 1 receptor (CRF1R). We identified and characterized seven novel cyclotides. One cyclotide, caripe 8, isolated from the most active fraction, was further analyzed and found to antagonize the CRF1R. A nanomolar concentration of this cyclotide (260 nM) reduced CRF potency by ~4.5-fold.

All published cyclotide solution structures exhibit a similar fold that forces the exposure of a hydrophobic patch to the surface. The homology model shown in Figure 5 suggests that, at least for Z. mays D, if a cystine knot is present then a hydrophobic surface will be exposed to the surface. It can be seen that the hydrophobic residues from loops 2 and 3 form a hydrophobic patch along one face of the molecule, with charged residues and additional hydrophobic residues arranged on the other face, as is the case in the bracelet cyclotides (Felizmenio-Quimio et al., 2001). It can be seen in Figure 6 that, at least for the sequences with typical loop 1 spacing, the conservation of hydrophobic residues suggests that a similar situation could occur for these proteins. The importance of the solvent-exposed hydrophobic patches for the natural function of the cyclotides is not known, but the high degree of sequence similarity between the Poaceae sequences and cyclotides may indicate that they are ...

Establishing structure activity relationships (SARs) in hit identification during early stage drug discovery is important in accelerating hit confirmation and expansion. We describe the development of En Core, a systematic molecular scaffold enumeration protocol using single atom mutations, to enhance the application of objective scaffold definitions and to enrich SAR information from analysis of high-throughput screening output. A list of 43 literature medicinal chemistry compound series, each containing a minimum of 100 compounds, published in the Journal of Medicinal Chemistry was collated to validate the protocol. Analysis using the top representative Level 1 scaffolds this list of literature compound series demonstrated that EnCore could mimic the scaffold exploration conducted when establishing SAR. When EnCore was applied to analyze an HTS library containing over 200 000 compounds, we observed that over 70% of the molecular scaffolds matched extant scaffolds within the library after ...

Entanglement and knots are naturally occurring, where, in the microscopic world, knots in DNA and homopolymers are well characterized. The most complex knots are observed in proteins which are harder to investigate, as proteins are heteropolymers composed of a combination of 20 different amino acids with different individual biophysical properties. As new-knotted topologies and new proteins containing knots continue to be discovered and characterized, the investigation of knots in proteins has gained intense interest. Thus far, the principle focus has been on the evolutionary origin of tying a knot, with questions of how a protein chain `self-ties into a knot, what the mechanism(s) are that contribute to threading, and the biological relevance and functional implication of a knotted topology in vivo gaining the most insight. Efforts to study the fully untied and unfolded chain indicate that the knot is highly stable, remaining intact in the unfolded state orders of magnitude longer than first ...
