GENETIC STUDIES ON MUTANT ENZYMES IN MAIZE. III. CONTROL OF GENE ACTION IN THE SYNTHESIS OF pH 7.5 ESTERASE

“…tissue. Three alleles of this gene designated E", E", and E" have been found in maize (SCHWARTZ 1960). The isozymes specified by these alleles are easily distinguishable in starch gel electrophoresis.…”

“…If, on the other hand, the inactivation of the E'" allele were gradual, these endosperms would show only the hybrid FS isozyme in addition to the NN with only very little, if any, FF isozyme. With random association, most of the sparse product of the less-active EF' allele would associate with the more abundant product of the still-active Es allele to form hybrid enzyme, as is the case with the product of the single paternal allele in heterozygous, triploid endosperm tissue ( SCHWARTZ 1960).…”

Alpha-Chymotrypsin Experimental Evaluation in the Treatment of Vitreous Haemorrhages

“…Hence no conclusion could be reached regarding the ability of the enzyme to cause an allergic reaction as suggested by Schwartz and Schwartz (1960).…”

“…The biochemical and pharmacological properties of alpha-chymotrypsin have been elaborately discussed by Schwartz and Schwartz (1960) who showed that the enzyme hydrolyses peptides at various points. The specificity of these sites distinguished this enzyme, although it can also hydrolyse other bonds such as esters and amides.…”

Erythrocyte Esterase Forms Controlled by Multiple Alleles in the Deer Mouse

“…. The fact that no hybrid enzymes were observed in lysates from Es-la Es-lb heterozygotes, as observed in heterozygous maize tissue ( SCHWARTZ 1960( SCHWARTZ ,1964, suggns s that the esterases produced by alleles Es-la and Es-lb are composed of a single polypeptide or aggregates of polypeptides produced by a single allele.…”
