Abstract
Human lysozyme and hen egg-white lysozyme have antibacterial, antiviral, and antifungal properties with numerous potential commercial applications. Currently, hen egg-white lysozyme dominates low cost applications but the recent high-level expression of human lysozyme in rice could provide an economical source of lysozyme. This work compares human lysozyme and hen egg-white lysozyme adsorption to the cation exchange resin, SP-Sepharose FF, and the effect of rice extract components on lysozyme purification. With one exception, the dynamic binding capacities of human lysozyme were lower than those of hen egg-white at pH 4.5, 6, and 7.5 with ionic strengths ranging from 0 to 100 mM (5-20 mS). Ionic strength and pH had a similar effect on the adsorption capacities, but human lysozyme was more sensitive to these two factors than hen egg-white lysozyme. In the presence of rice extract, the dynamic binding capacities of human and hen egg-white lysozymes were reduced by 20-30% and by 32-39% at pH 6. Hen egg-white lysozyme was used as a benchmark to compare the effectiveness of human lysozyme purification from transgenic rice extract. Process simulation and cost analyses for human lysozyme purification from rice and hen egg-white lysozyme purification from egg-white resulted in similar unit production costs at 1 ton per year scale.

Abstract
Two lysozymes were purified from quail egg white by cation exchange column chromatography and analyzed for amino acid sequence. The enzymes showed the same pH optimum profile for lytic activity with broad pH optima (pH 5.0-8.0) but had difference in mobility on native-PAGE. The native-PAGE immunoblot showed one or two lysozymes present in individual egg whites. The established amino acid sequence of quail egg white lysozyme A (QEWL A) was the same as quail lysozyme reported by Kaneda et al. [Kaneda, M., Kato, I., Tominaga, N., Titani, K., Narita, K., 1969. The amino acid sequence of quail lysozyme. J. Biochem. (Tokyo). 66, 747-749] and had six amino acid substitutions at position 3 (Phe to Tyr), 19 (Asn to Lys), 21 (Arg to Gln), 102 (Gly to Val) 103 (Asn to His) and 121 (Gln to Asn) compared to hen egg white lysozyme. QEWL A and QEWL B showed one substitution, at the position 21, Gln replaced by Lys, plus an insertion of Leu between position 20 and 21, being the first report that QEWL B had 130 amino acids. The amino acid differences between two lysozymes did not seem to affect antigenic determinants detected by polyclonal anti-hen egg white lysozyme, but caused them to separate well from each other by ion exchange chromatography.

Abstract
The energetics of association of the murine anti-hen egg lysozyme antibody HyHEL-5 with bobwhite quail lysozyme, California quail lysozyme, and the Arg45-->Lys mutant of hen egg lysozyme was characterized by isothermal titration calorimetry. The association of each lysozyme with HyHEL-5 is enthalpically driven in the temperature range 10 degrees C to 37 degrees C. The calorimetric results indicate that the salt-links between Arg45 and Arg68 of hen egg lysozyme and GluH50 on the HyHEL-5 paratope are energetically important in HyHEL-5/HEL association. In contrast to previous studies, the results suggest that the three characteristic 'quail' mutations affect the energetics of antibody/antigen association, even though they are buried and not in direct contact with the antibody.

Abstract
The HyHEL-5 antibody has more than a thousandfold lower affinity for bobwhite quail lysozyme (BWQL) than for hen egg-white lysozyme (HEL). Four sequence differences exist between BWQL and HEL, of which only one is involved in the interface with the Fab. The structure of bobwhite quail lysozyme has been determined in the uncomplexed state in two different crystal forms and in the complexed state with HyHEL-5, an antihen egg-white lysozyme Fab. Similar backbone conformations are observed in the three molecules of the two crystal forms of uncomplexed BWQL, although they show considerable variability in side-chain conformation. A relatively mobile segment in uncomplexed BWQL is observed to be part of the HyHEL-5 epitope. No major backbone conformational differences are observed in the lysozyme upon complex formation, but side-chain conformational differences are seen in surface residues that are involved in the interface with the antibody. The hydrogen bonding in the interface between BWQL and HyHEL-5 is similar to that in previously determined lysozyme-HyHEL-5 complexes.

Abstract
Polyclonal antisera elicited by evolutionary variants of bird lysozymes c played a major role in the development of the multideterminant-regulatory model to describe the antigenic structure of globular proteins and in the demonstration that there is a strong correlation between immunological differences and amino acid sequence differences. This chapter reviews the evidence and calculations used to show, for lysozyme c and several other proteins, the essentially the entire surface of globular proteins is antigenic, that nearly all evolutionary substitutions affect immunological cross-reactivity, and that there is empirical and theoretical support for the use of immunological distances to infer genealogical relationships and establish approximate evolutionary time scales. In addition this chapter discusses several examples of the use of polyclonal antisera to lysozymes c and g to gain insights into molecular and organismal evolution and the regulation of gene expression.

Abstract
We report the 470-MHz (11.7 T) 19F solution nuclear magnetic resonance (NMR) spectra of 2-, 3-, and 4-fluorophenylalanine incorporated into the egg white lysozymes (EC 3.2.1.17) of chicken, pheasant, and duck, as well as spectra of 4-fluorotryptophan incorporated into chicken, California valley quail, and Bob White quail and 5- and 6-fluorotryptophan-labeled chicken lysozyme. The 19F solution NMR spectrum of [4-F]Phe hen egg white lysozyme (HEWL) consists of three sharp resonances, which span a total chemical shift range of 4.8 ppm (at p2H = 6.1). For [3-F]Phe HEWL, the chemical shift range is much smaller, 1.0 ppm (at p2H = 5.9), due presumably to the occurrence of fast phenyl ring flips about the C beta-C gamma bond axis. For [2-F]Phe HEWL, six resonances are observed, spanning a chemical shift range of 7.4 ppm (at p2H = 5.8), due to slow C beta-C gamma ring flips, i.e., both ring-flip isomers appear to be "frozen in" because of steric hindrance. Rotation of the [2-F]Phe residues remains slow up to 55 degrees C (p2H = 4.7). With the [F]Trp-labeled proteins, we find a maximal 14.6-ppm shielding range for [4-F]Trp HEWL but only a 2.8- and 2.4-ppm range for [5- and 6-F]Trp HEWL, respectively, due presumably to increased solvent exposure in the latter cases. Guanidinium chloride denaturation causes loss of essentially all chemical shift nonequivalence, as does thermal denaturation. Spectra recorded as a function of pH show relatively small chemical shift changes (< 1.4 ppm) over the pH range of approximately 1.2-7.8.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Penicillin-binding protein 5 is the most abundant penicillin-binding protein in the vegetative membranes of Bacillus subtilis and accounts for 95% of the D,D-carboxypeptidase activity of the cell. The structural gene for penicillin-binding protein 5 was mapped to a genetically conserved region near guaB at 0 degrees on the B. subtilis chromosome, and immunoassays revealed that there is conservation of this major penicillin-binding protein among related species.

Abstract
Structural and immunological properties of numerous arylsulfatase A enzymes (EC 3.1.6) were examined in order to assess the relationships among these enzymes in animals. Arylsulfatase A enzymes from all animals bind to a Concanavalin A-Sepharose column, consistent with the conclusion that they are all glycoproteins. At pH 7.5 the apparent mol. wts of the enzymes are 80-182 kDa, while at pH 4.5 the mammalian arylsulfatase A enzymes dimerize and exhibit apparent mol. wts in the range of 297-348 kDa, but the enzymes from opossum and other lower classes of animals do not aggregate at pH 4.5. The mammalian arylsulfatase A enzymes, which aggregate at pH 4.5, also bind to rabbit liver arylsulfatase A monomers immobilized on an Affi-Gel 10 matrix. The arylsulfatase A enzymes that were studied all exhibit the anomalous kinetic behavior regarded as characteristic of these enzymes. However, not all of the inactivated enzymes are reactivated by sulfate ions. Goat antiserum raised against homogeneous rabbit liver arylsulfatase A cross-reacts with all of the mammalian enzymes in Ouchterlony gel diffusion experiments, whereas the enzymes from lower classes of animals do not cross-react. Quantitative immunoprecipitation experiments demonstrate that the mammalian enzymes are very similar to each other, with greater than 60% primary sequence homology indicated, while arylsulfatase A from opossum and other lower classes of animals show only a partial immunological similarity with the mammalian enzymes. Taken together, the data suggest that the active site of the enzyme and the structural features of the protein are highly conserved during the evolution of the enzyme molecule.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Antisera specific for leucine aminopeptidase (LAP) were prepared. Using these antisera in immunodiffusion tests, the identity of LAP isolated from beef lens and kidney is demonstrated. The same pertains to hog lens and kidney LAP. As indicated by only partial fusion of the immunoprecipitates in immunodiffusion plates, leucine aminopeptidases isolated from hog and beef are antigenically similar but not identical. These tests also indicate substantial similarity between a component in human lens homogenates and bovine or hog LAP. Microcomplement fixation tests corroborate these observations and indicate that, under these conditions, LAP from beef lens and kidney, or hog lens and kidney, are indistinguishable. However, there is an approximate 8.5% amino acid sequence difference between beef and hog LAP. Microcomplement fixation tests with human lens homogenate also corroborate immunodiffusion results and indicate an approximate 19% amino acid sequence difference between beef and human LAP. These data establish that LAP is a species-specific enzyme and they indicate that it is not organ specific. Maximal complement fixation occurs at approximately 0.1 microgram antigen per tube in those assays in which pure aminopeptidases were tested. This permits standardization of the microcomplement fixation assay for LAP under these conditions. Maximal complement fixation occurs at 160-200 micrograms human lens homogenate per tube. Assuming that in this quantity of homogenate there is 0.1 microgram LAP, then it can be calculated that LAP comprises about 0.05% of the lens protein. This agrees closely with the percentage of LAP in hog and beef lenses. Thus, the reduced LAP activity reported for human lens tissue appears not to result from an absence of the enzyme but rather, may be due to diminished catalytic competency of the enzyme in aged human lens tissue (see Taylor and Juhngen , 1984). The unit evolutionary period, 4.7-5.8 X 10(6) years, indicates that LAP has been highly conserved during evolution.

Abstract
Citrate lyase (EC 4.1.3.6) isolated from Rhodopseudomonas palustris was investigated with regard to its kinetic properties and its subunit composition. This enzyme was inactivated by citrate lyase deacetylase (EC 3.1.2.-) of Rhodopseudomonas gelatinosa. A corresponding cross-reaction was measured with partially purified deacetylase of R. palustris and citrate lyase of R. gelatinosa. The three different subunit types (alpha, beta, and gamma) of citrate lyase from R. gelatinosa wee purified to homogeneity, and antibodies were prepared against each of the three subunits and against the native enzyme complex. In corresondence with the enzymatic interactions, immunological cross-reactions were found between anti-enzyme and anti-large subunit antibodies and citrate lyase from R. palustris. On the other hand, no immunological cross-reactions were detectable among each of the antibodies and citrate lyases from Enterobacter aerogenes, Streptococcus diacetilactis, and Clostridium sphenoides. Antibodies against the large subunit of citrate lyase inhibited the deacetylase, but antibodies against the middle and small subunits did not, indicating that the large subunits of citrate lyase are involved in binding the deacetylase.

Abstract
Microcomplement fication (MCF) is a rapid and most sensitive method for the quantitation of slight modifications on protein surfaces not accessible by other immunologic means. Single amino acid substitutions (0.7 percent sequence differences) are readily detected. A firm relationship between sequence information and immunologic distance as measured by MCF could be established. The rate of molecular evolution of homology proteins can be derived from MCF measurements without prior knowledge of primary structures.

Abstract
An immunological approach has been used for the study of alkaline phosphatase evolution in bacteria of the family Enterobacteriaceae. Antisera were prepared against alkaline phosphatase from Escherichia coli and Klebsiella aerogenes and tested against the unpurified alkaline phosphatases of 32 strains of enterobacteria by double diffusion and quantitative micro-complement fixation. The immunological relationships detected among the alkaline phosphatases of enterobacteria agree approximately with those reported for five other enzymes, as well as with the tryptic peptide pattern similarities found for two other enzymes, and with the relationships detected by interspecific deoxyribonucleic acid hybridization tests.

Abstract
Antisera were prepared against pure nicotinamide adenine dinucleotide-dependent d-lactic dehydrogenases of Lactobacillus leichmannii, L. jensenii, and L. fermenti. When tested against these three antisera, crude extracts of almost all species of Lactobacillus containing a d-lactic dehydrogenase give cross-reactions. Extensive pairwise comparisons between cross-reacting crude extracts by double diffusion experiments permit the recognition of groups of identical antigenic specificity among the lactic dehydrogenases of the various nomenspecies of Lactobacillus. The same groups are revealed by each of the three antisera. By analyses of spur formation, the groups of identical antigenic specificity can be arranged in order of decreasing similarity to the homologous d-lactic dehydrogenase used as the reference point. From the combined results obtained with the three antisera, a map of the antigenic relationships among the d-lactic dehydrogenases of lactobacilli can be constructed. Microcomplement fixation experiments with two of the three anti-d-lactic dehydrogenases antisera support the conclusions drawn from double diffusion experiments and provide a quantitative estimation of the antigenic relationships among the various d-lactic dehydrogenases. An antiserum was also prepared against the pure l-lactic dehydrogenase of L. acidophilus group III. It cross-reacts with extracts of almost all lactobacilli containing an l-lactic dehydrogenase. With respect to species that contain both d- and l-lactic dehydrogenases, this antiserum reveals the same groups of identical antigenic specificity as do the antisera directed against d-lactic dehydrogenases. Other than the genus Lactobacillus, only extracts of Leuconostoc cross-react with anti-d-lactic dehydrogenase. No extrageneric cross-reactions were obtained with the anti-l-lactic dehydrogenase.
