The Structure of a Sub Procedure

A transfer matrix procedure was developed to study the noise generation and transmission for complex stiffened and interconnected structures. It has been shown that transmitted noise levels in the interior are sensitive to the structural dynamic characteristics not only of the stiffened sidewall but also of the sub-structure to which random loads are applied. Significant differences were found in noise transmission characteristics and levels between a completely coupled case and an idealized condition where the response of a sub-structure is computed independently from the response of the noise transmitting sidewall. 

The question of the oxidation state of the heme iron with NO bound might in principle thought to be accessible by consideration of the Fe-N distance and bond angles. However, with respect to distance it is important to realize that X-ray structures do not in themselves determine distances such as that from Fe to N to sub-angstrom resolution. The procedure is to fit electron density using restraints frequently obtained from small molecule studies. Thus, unless the resolution of a protein... 

Figure 2.33 shows the map for elastase and chymotrypsin. Rose (1979) developed an algorithm approach that requires only X-ray atomic coordinates. In his approach, the three-dimensional problem is reduced to an analysis in a plane by projection of the C position onto a disclosing plane. According to this procedure, domains are iteratively decomposed into sub-domains. A method for recognition of domains in proteins was also developed by Wodak and Janin (1980). Two continuous domains were observed in the structure of serine proteases, trypsin, chymotrypsin, and elastase (Hartley and Shotton, 1971 Blow and Steitz, 1970 Birktoft and Blow, 1972 ...
