Von Willebrand factor type A (vWA) domain was originally found in the blood coagulation protein von Willebrand factor (vWF). Typically, the vWA domain is made up of approximately 200 amino acid residues folded into a classic a/b para-rossmann type of fold. The vWA domain, since its discovery, has drawn great interest because of its widespread occurrence and its involvement in a wide variety of important cellular functions. These include basal membrane formation, cell migration, cell differentiation, adhesion, haemostasis, signaling, chromosomal stability, malignant transformation and in immune defenses In integrins these domains form heterodimers while in vWF it forms multimers. There are different interaction surfaces of this domain as seen by the various molecules it complexes with. Ligand binding in most cases is mediated by the presence of a metal ion dependent adhesion site termed as the MIDAS motif that is a characteristic feature of most, if not all A domains.
The actual alignment was detected with superfamily member cd01456:

norD type: Denitrifying bacteria contain both membrane bound and periplasmic nitrate reductases. Denitrification plays a major role in completing the nitrogen cycle by converting nitrate or nitrite to nitrogen gas. The pathway for microbial denitrification has been established as NO3- ------> NO2- ------> NO -------> N2O ---------> N2. This reaction generally occurs under oxygen limiting conditions. Genetic and biochemical studies have shown that the first srep of the biochemical pathway is catalyzed by periplasmic nitrate reductases. This family is widely present in proteobacteria and firmicutes. This version of the domain is also present in some archaeal members. The function of the vWA domain in this sub-group is not known. Members of this subgroup have a conserved MIDAS motif.

vWA_interalpha trypsin inhibitor (ITI): ITI is a glycoprotein composed of three polypeptides- two heavy chains and one light chain (bikunin). Bikunin confers the protease-inhibitor function while the heavy chains are involved in rendering stability to the extracellular matrix by binding to hyaluronic acid. The heavy chains carry the VWA domain with a conserved MIDAS motif. Although the exact role of the VWA domains remains unknown, it has been speculated to be involved in mediating protein-protein interactions with the components of the extracellular matrix.

Magnesium chelatase: Mg-chelatase catalyses the insertion of Mg into protoporphyrin IX (Proto). In chlorophyll biosynthesis, insertion of Mg2+ into protoporphyrin IX is catalysed by magnesium chelatase in an ATP-dependent reaction. Magnesium chelatase is a three sub-unit (BchI, BchD and BchH) enzyme with a novel arrangement of domains: the C-terminal helical domain is located behind the nucleotide binding site. The BchD domain contains a AAA domain at its N-terminus and a VWA domain at its C-terminus. The VWA domain has been speculated to be involved in mediating protein-protein interactions.
