1257:-binding protein. Homotrimerisation is a process whereby three of the same subunits, associate to make a complex of three identical YadA proteins. Furthermore, just like other TAAs, it has a head-stalk-anchor protein architecture. The majority of TAAs share strong similarity in the C-terminal membrane anchor region, the only member to differ across TAAs is the head, neck, and stalk regions. The head region of YadA is composed of beta-helices further folded to create a nine-coiled left-handed parallel beta-roll (LPBR). 348:: This particular domain is a trimer of single-stranded, left-handed beta-helices. These associate to form a nine-coiled left-handed beta-roll. It contains sequence motifs, of which there is a strong similarity with other TAA heads. This indicates that there is a lot of similarity when comparing protein structure. The head domain is connected to the stalk by a short, highly conserved sequence, which is often called the neck, or occasionally named the connector. 3350: 706: 43: 1572: 1643:, since they have an outer membrane that makes it hard for them to stick to and infect the host. The outer membrane is useful, as it allows the bacteria to colonize, and adds another layer of protection. However, the outer membrane is a barrier for the secretion of proteins, and it requires energy to transport proteins across the outer membrane. Hence, the T5SS pathway overcomes this problem. 31: 1684:. The signal peptide on the N-terminus acts as a temporary tether to hold it in place. Next, it must move to the outer membrane. The trimerisation aids translocation, and no translocation would occur without its beta-barrel membrane anchor. The type V secretion system is described as non-fimbrious, meaning that the bacterial cells do not use long physical appendages named 329:: There are several roles that the Extended Signal Peptide Region is thought to hold. First, biogenesis of proteins in the Type V Secretion System (T5SS). Second, it is thought to target the protein to the inner membrane to be translocated either by the signal recognition particle pathway (SRP) or by twin 1293:
infections in humans. The structure of UspA1 also has a head domain at N-terminal domain, however it is folded into the beta propeller. Like the other TAAs, it has a coiled-coil stalk region but, in this case it is extended, and it has the TAA typical C-terminal beta barrel membrane anchor domain.

YadA-like head is composed of single-stranded, left-handed beta-helices, which associate further to create a nine-coiled left-handed parallel beta-roll (LPBR). It is the tightest beta-roll structure known, and the first to be discovered. The YadA head domain has eight repeat motifs, each fourteen

protrude forming knobs that pack into cavities formed by other residues on another helix. Then, once the knobs are packed into cavities, the three helices are wound in register around each other, so all of the residues in certain positions are at the same height.
389:
There are several types of head domain. Each domain helps the head to bind to a different component of the extracellular matrix. These are as follows: YadA-like head domain, Trp-ring, GIN, FxG, HIN1, and HIN2. This entry focuses on the first three mentioned.
488:
The ISneck domain is a type of neck domain. There are two types of ISneck domain. This first is an ISneck which is interrupted by an insertion. The insertion can take form of either folded (ISneck 1) or much shorter, unfolded (ISneck 2) perturbation.
311:. The function of the ESPR is to aid inner membrane translocation by acting as a temporary tether. This prevents the accumulation of misfolded proteins. The ESPR can be divided into individual regions, they are as follows: N1 (charged), H1 ( 476:
and the smaller one of the coiled coil. Furthermore, just like its safety pin structure, it also has a function of pinning all three monomers together and pins it to the head domain. This increases the stability of the neck domain.

Trimeric autotransporter adhesins have a unique structure. The structure they hold is crucial to their function. They all appear to have a head-stalk-anchor structure. Each TAA is made up of three identical proteins, hence the name

185:, referring to the C-terminal membrane anchor. Although all TAAs carry a membrane anchor in common, they may not all contain both a stalk and a head as well. In addition, all membrane anchor domains are of the left-handed parallel 629:: These domains are fibrous and found in highly repetitive numbers. They contain coiled coils and their length tends to vary among different species. The coiled-coil segments of the stalk domains have two unusual properties: 1252:

There are seven different type of neck domains. They are as follows: ISneck1, ISneck2, HANS connector, DALL-1, DALL-2, DALL-3, and the neck domain. This entry focuses on the ISneck domain.
