In protein's structural motifs describes the connectivity between the secondary structural elements, let's say sse in short.
00:12
In addition to these secondary structural elements, protein structural motives includes loops of variable length and unspecified, let's say unsp structures, let's say sdr.
00:27
The structural motives can also appear.
00:30
In the form of tandem repeats.
00:36
Now examples of structural motives can be number one the beta hair pin structural motif.
00:46
Now this is the most common structure which comprises of two anti -parallel, let's say ap in short, beta strands connected by a tight turn of a few amino acids between them.
01:06
The second structural motive is called as the greek key.
01:11
Now this comprises of four beta strands wherein three of them are connected by the hair pins and the fourth one is folded over the top.
01:28
The third example is the zinc finger.
01:33
Now this structural motif comprises of two beta strands with an alpha helix end folded over to bind to a zinc ion.
01:47
Now this is very important in the dna binding proteins.
01:54
Now let us consider the structural motives that tend to promote the protein dimerization.
02:05
Let's say dmz.
02:08
The first one is the lucin zipper, let's say lz in short.
02:13
The second one is the helix loop helix...
