Sortase refers to a group of prokaryotic enzymes that modify surface proteins by recognizing and cleaving a carboxyl-terminal sorting signal. For most substrates of sortase enzymes, the recognition signal consists of the motif LPXTG (Leu-Pro-any-Thr-Gly), then a highly hydrophobic transmembrane sequence, followed by a cluster of basic residues ...
The motif contains a tyrosine separated from a leucine or isoleucine by any two other amino acids, giving the signature YxxL/I. Two of these signatures are typically separated by between 6 and 8 amino acids in the cytoplasmic tail of the molecule (YxxL/Ix (6-8) YxxL/I). However, it is worth noting that in various sources, this consensus ...
A DNA sequence motif represented as a sequence logo for the LexA-binding motif. In biology, a sequence motif is a nucleotide or amino-acid sequence pattern that is widespread and usually assumed to be related to biological function of the macromolecule. For example, an N -glycosylation site motif can be defined as Asn, followed by anything but ...
Tandem repeat describes a pattern that helps determine an individual's inherited traits. Tandem repeats can be very useful in determining parentage. Short tandem repeats are used for certain genealogical DNA tests. DNA is examined from microsatellites within the chromosomal DNA.
CpG oligodeoxynucleotides (or CpG ODN) are short single-stranded synthetic DNA molecules that contain a cytosine triphosphate deoxynucleotide ("C") followed by a guanine triphosphate deoxynucleotide ("G"). The "p" refers to the phosphodiester link between consecutive nucleotides, although some ODN have a modified phosphorothioate (PS) backbone ...
Grateful dead (or grateful ghost) is both a motif and a group of related folktales present in many cultures throughout the world. The most common story involves a traveler who encounters a corpse of someone who never received a proper burial, typically stemming from an unpaid debt. The traveler then either pays off the dead person's debt or ...
Textile design, also known as textile geometry, is the creative and technical process by which thread or yarn fibers are interlaced to form a piece of cloth or fabric, which is subsequently printed upon or otherwise adorned. [1] Textile design is further broken down into three major disciplines: printed textile design, woven textile design, and ...
Motif discovery tools can be split into two major categories, discovery of novel instance of known functional motifs class and discovery of functional motifs class, however, they all use a limited and overlapping set of attributes to discriminate true and false positives. The main discrimatory attributes used in motif discovery are:
