Polypyrrole properties, in contrast to the PEDOT case, are very sensitive to selection of the substrate material (Pt or Pt/TiO2) during electropolymerization.
The size of the amplifier is miniaturized by incorporating innovative design techniques and proper selection of the substrate material in the input/output matching networks.
Each NRPS or PKS module contains a series of domains; a minimum NRPS module consists of condensation (C) domain for catalysing peptide bond formation, an adenylation (A) domain for selection of the substrate, and a peptide carrier protein (PCP) domain.
In 1966, Dunathan [ 14] provided a unifying concept for the specific selection of the substrate scissile bond in PLP-dependent enzymes, which has been confirmed in solution and structural studies.
However, CLSM allowed us to determine the percentage of live/dead bacteria in our isolates, so we believe that this technique is still useful for the study of more detailed aspects of biofilms, although selection of the substrate appears to be important for the study of particular strains, because of the observed differences between them.
Chemical attraction toward fermentation products produced by microorganisms that live on food sources and aggregation pheromones emitted by recently mated adult female fruit flies play a directive role in the selection of these substrates (Hutner et al., 1937; West, 1961; Bartelt et al., 1985; Wertheim, 2001).
It should be noted that the initial substrates and network configuration of the initial pathway-map network depended on the order of selection of the initial substrate and the product being connected.
One of the main difficulties in the selection of alternative substrates includes finding the appropriate composition that allows cell growth and accumulation of the product of interest.
As evident during ERAD, molecular chaperones play an important role during the selection of cytoplasmic substrates and, once selected, the proteins are also ubiquitylated and degraded by the proteasome.
A similar strategy, but applied to the second partner of the antibody antigen pair, may result in selection of complementary substrates to the chosen Ig.
