... cover the sequence segments within the C-terminal extracellular domain. The segments correspond, in fact, with some of the a-amylase family CSRs, namely the b-strands b2, b3, b4 and b8 of the (b ... have it [9,19,24,25]. The main goal of the present study was to investi- gate further the resemblance between hcHAT proteins and the enzymes from the a-amylase family. We t...

... are located within three of these polypeptides: cytochrome b, cytochrome c 1 and the Rieske iron-suphur protein (ISP). The [2Fe)2S] prosthetic group of the ISP is located within the soluble C-terminal ... Studies of the mechanism of assembly of the bc 1 complex suggest that the ISP is one of the last subunits to be integrated within the membrane-bound subcomplex [2]....

... studies indicate that there is a controversy in the literature about the impor- tance of the CagL RGD-motif in T4SS functions and host cell signalling. Another unsolved question is the proposed structure ... and that the carboxy-terminal interaction of CagY with integrin b1 has a different function, further confirming that the observed cell spreading effect is specific for CagL. Whe...

Additionally, only those two ADAMs lack the RX(6)DLPEFa(9)b(1) integrin binding motif, which is contained in the other members of the pro- teinase family [48]. Neverthele...
