Abstract
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 showed that the process of casein micelle aggregation induced by CpCP3 was similar to that caused by chymosin. The cheeses made using CpCP3 showed higher moisture content than those made with chymosin, but protein, fat, and ash were similar. The sensory analysis showed that cheeses made with CpCP3 had high acceptance index (>80%). In silico analysis predicted the presence of only two short allergenic peptides on the surface of CpCP3, which was highly susceptible to digestive enzymes and did not alter zebrafish embryos' morphology and development. Moreover, recombinant CpCP3 was expressed in Escherichia coli. All results support the biotechnological potential of CpCP3 as an alternative enzyme to chymosin.

Abstract
Due mainly to properties such as high affinity and antigen specificity, antibodies have become important tools for biomedical research, diagnosis, and treatment of several human diseases. When the objective is to administer them for therapy, strategies are used to reduce the heterologous protein immunogenicity and to improve pharmacokinetic and pharmacodynamic characteristics. Size minimization contributes to ameliorate these characteristics, while preserving the antigen-antibody interaction site. Since the discovery that camelids produce functional antibodies devoid of light chains, studies have proposed the use of single domains for biosensors, monitoring and treatment of tumors, therapies for inflammatory and neurodegenerative diseases, drug delivery, or passive immunotherapy. Despite an expected increase in antibody and related products in the pharmaceutical market over the next years, few research initiatives are related to the development of alternatives for helping to manage neglected tropical diseases (NTDs). In this review, we summarize developments of camelid single-domain antibodies (VHH) in the field of NTDs. Particular attention is given to VHH-derived products, i.e., VHHs fused to nanoparticles, constructed for the development of rapid diagnostic kits; fused to oligomeric matrix proteins for viral neutralization; and conjugated with proteins for the treatment of human parasites. Moreover, paratransgenesis technology using VHHs is an interesting approach to control parasite development in vectors. With enormous biotechnological versatility, facility and low cost for heterologous production, and greater ability to recognize different epitopes, VHHs have appeared as an opportunity to overcome challenges related to the prevention, detection, and control of human diseases, especially NTDs.

Abstract
A gene circuit for the controlled expression of a marker gene and for the assay of xylose concentration in Escherichia coli has been designed and tested. The xylF coding sequence for the xylose binding protein (XBP) was cloned in pT7T318U downstream from the promoter for xylanase A from B. subtilis (Pbsu), together with the GFP coding sequence (gfp) under the control of the xylF promoter, forming the pT7T3-GFP-XBP construct. GFP fluorescence in Escherichia coli JW3538-1 xylF-transformed with pT7T3-GFP-XBP was approximately 1.4 × higher after 520 min growth in the presence of 5mM xylose than in cells transformed with pT7T3-GFP. Under saturating xylose concentration, flow cytometry analysis showed that all cells resulted in homogeneous populations, and the population with XBP showed a fluorescence greater than that without XBP. Activity of the xylF promoter in cells transformed with pT7T3-GFP-XBP was ≈ 40% higher than with the pT7T3-GFP. No response was observed with arabinose and ribose, showing that the expression effects were specific for xylose, demonstrating the potential use of the gene circuit as a biosensor.

Abstract
Xyloglucan is a major structural polysaccharide of the primary (growing) cell wall of higher plants. It consists of a cellulosic backbone (beta-1,4-linked glucosyl residues) that is frequently substituted with side chains. This report describes Aspergillus nidulans strain A773 recombinant secretion of a dimeric xyloglucan-specific endo-β-1,4-glucanohydrolase (XegA) cloned from Aspergillus niveus. The ORF of the A. niveus xegA gene is comprised of 714 nucleotides, and encodes a 238 amino acid protein with a calculated molecular weight of 23.5kDa and isoelectric point of 4.38. The optimal pH and temperature were 6.0 and 60°C, respectively. XegA generated a xyloglucan-oligosaccharides (XGOs) pattern similar to that observed for cellulases from family GH12, i.e., demonstrating that its mode of action includes hydrolysis of the glycosidic linkages between glucosyl residues that are not branched with xylose. In contrast to commercial lichenase, mixed linkage beta-glucan (lichenan) was not digested by XegA, indicating that the enzyme did not cleave glucan β-1,3 or β-1,6 bonds. The far-UV CD spectrum of the purified enzyme indicated a protein rich in β-sheet structures as expected for GH12 xyloglucanases. Thermal unfolding studies displayed two transitions with mid-point temperatures of 51.3°C and 81.3°C respectively, and dynamic light scattering studies indicated that the first transition involves a change in oligomeric state from a dimeric to a monomeric form. Since the enzyme is a predominantly a monomer at 60°C, the enzymatic assays demonstrated that XegA is more active in its monomeric state.

Abstract
Two bifunctional enzymes exhibiting combined xylanase and laccase activities were designed, constructed, and characterized by biochemical and biophysical methods. The Bacillus subtilis cotA and xynA genes were used as templates for gene fusion, and the xynA coding sequence was inserted into a surface loop of the cotA. A second chimera was built replacing the wild-type xynA gene by a thermostable variant (xynAG3) previously obtained by in vitro molecular evolution. Kinetic measurements demonstrated that the pH and temperature optima of the catalytic domains in the chimeras were altered by less than 0.5 pH units and 5 °C, respectively, when compared with the parental enzymes. In contrast, the catalytic efficiency (k(cat)/K(m)) of the laccase activity in both chimeras was 2-fold higher than for the parental laccase. Molecular dynamics simulations of the CotA-XynA chimera indicated that the two domains are in close contact, which was confirmed by the low resolution structure obtained by small angle x-ray scattering. The simulation also indicates that the formation of the inter-domain interface causes the dislocation of the loop comprising residues Leu-558 to Lys-573 in the laccase domain, resulting in a more accessible active site and exposing the type I Cu(2+) ion to the solvent. These structural changes are consistent with the results from UV-visible electronic and EPR spectroscopy experiments of the type I copper between the native and chimeric enzymes and are likely to contribute to the observed increase in catalytic turnover number.
