Selectivity SERS

Systems In nonaqueous systems [87], the amount of water is very limited, coming from trace water that remains after purification of these solvents or from water intentionally added to the solvent. The extensive hydrogen bonding of bulk water is broken, resulting in vq-h bands of greater resolution than observed in aqueous media. Fig. 41 gives selected SERS spectra of water in different solvents using LiBr as the electrolyte.

According to Anh s theory, the cyclopentadienes having snbstitutents of second and third row elements such as SR and SeR at the 5-positions are expected to react with syn n facial selectivity since the stabilization dne to n-jt interaction in such systems is larger than 1. The observation contradicted the prediction [3,4,7]. We and Ohwada... 

The second cell-specific regulatory element within the distal enhancer is named SER. Loss of this element, which is at the extreme distal edge of the enhancer, leads to a selective loss of DDC expression in the ventral lateral serotonin cells (Johnson et al., 1989 Lundell and Hirsh, 1992) (Fig. 6C). This element has been delimited to about 40 bp and shows unexpected complexity, consisting of two functionally redundant elements. These two subelements, SERl and SERr, are each sufficient to allow normal DDC expression in the ventral lateral serotonin neurons if the other is deleted. In spite of this functional similarity, no sequence similarity is apparent between the two regions. The region of conservation between D. melanogaster and D. virilis is limited to SERl. 

As described in more detail below, agonist binding will lead to signaling as well as phosphorylation of Ser and Thr residues, especially, but also, in selected cases, Tyr residues located in intracellular loop-3 and in the C-terminal extension. This post-translational modification alters the affinity of the receptor for various intracellular proteins, including arrestin, which sterically prevents further G-protein binding and functions as an adaptor protein. Also, interaction with other types of scaffolding proteins such as PSD-95-like proteins, is influenced by the phosphorylation state of the receptor.
