in the 1990 s
The residue at position 226 in the S1-subsite of graspases is responsible for substrate specificity, whereas the residue crucial for specificity in classical serine proteases is located at position 189.
      
The O-specific polysaccharide chain in the S-LPS macromolecule increases the affinity of its interaction with porin in comparison with R-LPS-porin binding.
      
These effects make it possible to explain the broadening of the spectrum, the stable distribution of the visualization pattern, and the appearance of irregularities in the oscillograms observed in the S transition.
      
The additional photoluminescence band with a maximum in the range of 440 nm at 10 K is assigned to the transition B""3Πu → X3Σg- in the S2 molecule.
      
The particle size decreases with an increase in the S/Au ratio.
      
It was shown that in the S0 state, the azide group in all the azides has quasi-linear geometry and a significant positive charge on the two terminal nitrogen atoms.
      
As a result, the σNN* orbital is not populated in the S1 state when a particular threshold size of the π system is achieved, and the azide becomes photo-inactive.
      
The σNN* antibonding orbital at the N-N2 bond was occupied in both of the azides in the S1 state; this fact is consistent with the photochemical activity of these compounds.
      
It was shown that the σNN* molecular orbital, which is localized on the azide group and is antibonding for the N-N2 bond, is populated in the S1 state of these azides in both neutral and protonated forms.
      
The parameters of an ST-10XME CCD camera incorporated in the S180 spectrometer have been studied, and a mathematical model describing its characteristics has been developed.
      
The quenching mechanism was studied and the results suggested that both dynamic and static quenching processes were responsible for the observed positive deviation in the S-V plot.
      
The S10 operon includes genes for 20 ribosomal proteins, Sec Y transport protein, adenylate kinase, and methionine aminopeptidase, and lacks theinfA-rpl36-rps13-rpoA-rpl17 genes found in the S10 operon ofM.
      
Genomic Southern blot analysis indicates the presence of a small family of SsPto in the S.
      
SsPto is found to be constitutively expressed in the S.
      
The process of spore formation was restored in the S revertants, but they differed both from the wild type and from each other.
      
Inflections in the S-shaped dependence of the HNO3 concentration in the organic phase on the [Zr]:[HDBP] molar ratio lie within the interval from 1:8 to 1:12, which corresponds to filling of the Zr outer sphere with HDBP molecules.
      
The analysis of labeled mitosis showed that some cells infected in the S phase ceased to progress through the cell cycle at one of its phases (S, G2, or M); at the same time, at least part of the infected cells remained capable of entering mitosis.
      
The potential surfaces of (2π + 2π) cyclization of bis(3-thioxo-1-propenyl) sulfide in the S0, T1, and S1 states were studied using quantum-chemical methods of molecular simulation.
      
In the S0 and S1 states, the cyclization yields a thiabicyclic structure.
      
In some rye lines, the mutations of self-fertility were identified in the S, Z, or T incompatibility loci.
