¹ Sequence changes at protein level following the Nomenclature for Description of Genetic Variations approved by Human Genome Variation Society (HGVS). (isth.org)
In the genome of the grey mould fungus Botrytis cinerea , genes encoding three hydrophobins and six hydrophobin-like proteins were identified. (biomedcentral.com)

Recombinant expression of protein in Escherichia coli often results in the formation of insoluble protein aggregates called inclusion bodies. (wikipedia.org)
These protein bodies require refolding in vitro once extracted from E.coli cells by strong detergent. (wikipedia.org)
E.coli was clearly more appropriate for these kinds of proteins. (europa.eu)
The latter can replace E. coli YidC for Sec-independent insertion of proteins ( Bloois et al . (tcdb.org)

functional proteins. (lu.se)
PROT data base (6) of functional proteins, this method yields model containing only two amino acid types, hydrophobic and clear evidence for nonrandomness. (lu.se)

The protein is coloured grey, the side chains of both the wild-type and the mutant residue are shown and coloured green and red respectively. (cortell.net)

With cross-linking studies, it could be shown that the hydrophobicity of the signal sequence is crucial for SRP binding, since lowering the hydrophobicity resulted in less efficient cross-linking 15 , 16 . (nature.com)
A crucial residue that stabilises the equilibrium structure of the DBD fold itself is a cysteine residue situated in the hydrophobic core of all known nuclear hormone receptors (but not involved in metal binding): it appears to be conserved absolutely for its unique combination of size and hydrophobicity. (ox.ac.uk)
Whether for research or quality control purposes, it is crucial to differentiate between proteins. (ftloscience.com)

Folding of proteins that are difficult to do in the cytoplasm can be enhanced in the periplasm where the osmotic pressure can be readily controlled. (wikipedia.org)
The functions on cytoplasm show 10.82 isoelectric point and 48.6% hydrophobicity. (researchsquare.com)

This means that other homologous proteins exist with that other residue type than with the wild-type residue in my protein sequence, but the other residue type is not similar to my mutant residue. (cortell.net)

Use measure sasa to define an "area" attribute of residues, then assign residue hydrophobicities from a file with the defattr command, and then use a single select command to intersect these two attributes. (github.io)
In the defattr example files I already happened to include a file kdHydrophobicity.txt to assign Kyte-Doolittle hydrophobity, as well as for several other hydrophobicity scales. (github.io)

dom hydrophobicity distributions fold well. (lu.se)

The original wild-type residue and newly introduced mutant residue differ in these properties: the mutant residue is smaller than the wild-type residue, while the wild-type residue is more hydrophobic than the mutant residue. (cortell.net)
The mutant residue is smaller than the wild-type residue. (cortell.net)
The hydrophobicity of the wild-type and mutant residue differs. (cortell.net)

SRP is bound to the ribosome and is ready to interact with a nascent protein chain. (nature.com)
Significantly the center from the hydrophobic extend offers three Pro residues and one Ser residue that could interact among themselves to create a "Pro knot " therefore creating a non-polar hairpin structure having a switch of 12 residues and two hands each of 30 residues. (liveconscience.com)
Twenty-one amino acid residues of RdRp were found to interact with ivermectin including the catalytic residue Asp760. (pharmacare.store)

This suggests that these residues are key for UMAMIT29-mediated glucosinolate transport activity and thus potential targets for blocking the transport of glucosinolates to the seeds. (frontiersin.org)
This feature suggests that proteolysis will most likely happen within the hydrophilic portions of AUY922 inhibition proteins, because these revealed parts would be more accessible for cleavage. (biopaqc.com)

however, a short molecular recognition feature (MoRF) likely spans residues 3-7. (biorxiv.org)

Natural amino acids are the only ones to have the L configuration and are exclusively present in proteins during translation in the ribosome, with the exception of achiral glycine. (easy4learning.com)

However, with an unfunctionalized surface, this technique suffers from a lack of known binding specificity which can denature the protein and result in a loss in activity. (clemson.edu)

The human cuticle is around 6 to 8 layers thick and consists of keratin protein, structural lipids, and high sulfur keratin-associated proteins (KAP). (thieme-connect.com)
10 , 11 Studies attempting to predict the secondary structural elements of this protein indicate one α-helix and, depending on the study, two β-strands. (biorxiv.org)
Protein functional properties are determined to a large extent by a protein s physicochemical and structural properties ( Diniz and Martin, 1997 ). (scialert.net)
2019). 3Clpro and Plpro are two important virus proteases that catalyse the processing of polyproteins pp1a and pp1ab leading to the formation of RdRp and other important non-structural proteins (nsp) (Anand et al. (pharmacare.store)

Proteins can differ slightly, such as bovine (cow) insulin and human insulin having the same length but different amino acids at three locations. (ftloscience.com)
