Molecular characteristics of luciferase. A molecule of the luciferase of G. polyedra comprises three homologous domains (Li et al., 1997 Li and Hastings, 1998). The full-length luciferase (135 kDa) and each of the individual domains are most active at pH 6.3, and they show very little activity at pH 8.0. Morishita et al. (2002) prepared a recombinant Pyrocystis lunula luciferase consisting of mainly the third domain. This recombinant enzyme catalyzed the light emission of luciferin (luminescence A.max 474 nm) and the enzyme was active at pH 8.0. The recombinant enzyme of the third domain of G. polyedra luciferase was crystallized and its X-ray structure was determined (Schultz et al., 2005). A -barrel pocket putatively for substrate binding and catalysis was identified in the structure, and...

The descriptors used should not be highly collinear with each other, for two reasons. First, this can lead to statistical instability and overprediction, and second, collinearity makes mechanistic interpretation difficult. For example, Cronin and Schultz [41] have pointed out that although a good correlation could be obtained between the skin sensitization potential and the hydrophobicity of a series of bromoalkanes, a correlation between skin sensitization potential and molecular weight had exactly the same statistics, because hydrophobicity and molecular weight are very highly correlated in homologous series.

Schultz and Linden Ind. Eng. Chem. Process Design and Development, 1 (111), 1962] have studied the hydrogenolysis of low molecular weight paraffins in a tubular flow reactor. The kinetics of the propane reaction may be assumed to be first-order in propane in the regime of interest. From the data below determine the reaction rate constants at the indicated temperatures and the activation energy of the reaction.

Most of the commonly used electronic-structure methods are based upon Hartree-Fock theory, with electron correlation sometimes included in various ways (Slater, 1974). Typically one begins with a many-electron wave function comprised of one or several Slater determinants and takes the one-electron wave functions to be molecular orbitals (MO s) in the form of linear combinations of atomic orbitals (LCAO s) (An alternative approach, the generalized valence-bond method (see, for example, Schultz and Messmer, 1986), has been used in a few cases but has not been widely applied to defect problems.)...

The question P.G. Schultz, from Berkeley, and R.A.Lemer, from Scripps, set forth was "How to associate the prodigious capacity of molecular recognition of antibodies with potential enzymatic (catalytic) activity " [22a] [26]. In 1986, they succeeded developing the first antibodies with catalytic activity [27]. Lemer called them abzymes. In fact, their strategy is quite simple based on Pauling s hypothesis, Lerner s and Schultz s groups looked for antibodies that could stabilise the transition state of a given reaction, such as ester and carbonate hydrolysis. 

While the catalysts and conditions are very different than in ZN (water is a severe poison for ZN but is a product in FT), both produce linear polymers, and the molecular weight distributions are very similar because they are controlled by relative rate coefficients of propagation kp and termination k. If these are nearly independent of molecular weight one obtains the Schultz Flory size distribution in both processes.

High acute doses of ionizing radiation produce adverse biological effects at every organizational level molecular, cellular, tissue-organ, whole animal, population, community, and ecosystem (ICRP 1977 Whicker and Schultz 1982b LWV 1985 Hobbs and McClellan 1986 UNSCEAR 1988 Kiefer 1990 Severn and Bar 1991).

An extensive list of volatile compounds in apples and other fruits was included in a review by Nursten (222). White (223) reported that the principal components of the aroma of apples were alcohols (92% ) methanol, ethanol, 1-propanol, 2-propanol, 1-butanol, 2-methyl-l-propa-nol, 2-methyl-l-butanol, and 1-hexanol. The other constituents included 6% carbonyl compounds and 2% esters. Later, MacGregor et al. (224) tentatively identified 30 volatile components of McIntosh apple juice including four aldehydes, one ketone, 11 alcohols, 10 esters, and four fatty acids. The major organic volatiles in several different extractants of Delicious apple essence were identified and quantitatively estimated by Schultz et al. (225). They reported from sensory tests that low molecular weight alcohols contributed little to apple aroma. Flath et al. (226) identified... 

In contrast to the case for metals, positronium can be formed in the bulk of many insulators and molecular crystals, and any positronium which subsequently diffuses to the surface can be emitted into the vacuum with a kinetic energy < — Ps, where (f)Ps is the positronium work function. Its value can be expressed in terms of the binding energy of the positronium when in the solid, EB, and the positronium chemical potential, /xPs, as (Schultz and Lynn, 1988)... 

The fits of Janev et al. [12] stem from a compilation of the results obtained with different theoretical approaches (i) semi-classical close-coupling methods with a development of the wave function on atomic orbitals (Fritsch and Lin [16]), molecular orbitals (Green et al [17]), or both (Kimura and Lin [18], (ii) pure classical model - i.e. the Classical Trajectory Monte Carlo method (Olson and Schultz [19]) - and (iii) perturbative quantum approach (Belkic et al. [20]). In order to get precise fits, theoretical results accuracy was estimated according to many criteria, most important being the domain of validity of each technique.
