Globular regions

A micrograph reveals 10 black-etching needles and 8 globular regions that etch grey, set in a white-etching matrix. 

The class 1 MHC structure is divided into two globular regions (Figure 15.18). One region is built up from the two immunoglobulin-like domains a3...

Fig. 18. Schematic representation of the transmembrane orientation of cytochrome f based on the occurrence of a high proportion of charged residues for 1—250 (represented as a globular region), and hydrophobic residues 250-271 (believed to be helical and trans-membrane) [146]...

Collagen VI is a rodlike molecule about 105-nm long with two globular regions at the extremities (Fig. 2A Furthmayr et al., 1983). The globular regions contain several domains homologous to von Willebrand... 

Fragment 3 (Mr 50K) possessed / structure, appeared globular in electron micrographs, and was found to bind to heparin. It was assumed to be the globular region at the end of the long arm of laminin. This site is one of the main heparin- and heparan sulfate-binding domains in laminin (Ott et al., 1982). 

Let us return to Fig. 8, where the knot formation probability p is plotted as a function of the swelling ratio, a, in the globular region (a < 1). It can be seen that in the compression region, especially for a < 0.6, data of numerical simulation are absent. It is difficult to obtain such data because of the restricted capacity of computers. Really, it is necessary to calculate the Alexander polynomial for each generated closed contour. As mentioned above, it takes in the order of 0(l3) operations. This value is too large for the dense chain state because the denser the system is, the more selfcrossings l should be in the projection.

Figure 10.38. Structure of a Fibrinogen Molecule. (A) A ribbon diagram. The two rod regions are a-helical coiled coils, connected to a globular region at each end. (B) A schematic representation showing the positions of the fibrinopeptides A and B.
