The inhibition of yeast carboxylase by homologous antiserum.

THE INHIBITION OF d-GLYCERALDEHYDE 3-PHOSPHATE DEHYDROGENASE BY SPECIFIC ANTISERUM

Antibodies to yeast d-glyceraldehyde 3-phosphate dehydrogenase have been produced in rabbits and chickens. The antiserum from either animal inhibits the activity of the yeast enzyme with the formation of a precipitate that has a low residual activity. One combining site of antibody on the enzyme appears to be the point of DPN attachment. The rate of antigen-antibody formation has been studied w...

Immunological Study on the Structural Difference between Ribulose- 1,5-bisphosphate Carboxylase/Oxygenase from Nicotiana tabacum var. John William's Broadleaf and the Tobacco Mutant Su/su

In the present paper we have attempted to characterize by means of immunological methods the molecular difference between ribulose 1,5-bisphosphate carboxylase/oxygenase from the wild type TV. tabacum var. John William's Broadleaf and the tobacco mutant Su/su. The tobacco mutant Su/su exhibits in comparison to the wild type a higher photorespiratory activity. The reagents used in the present st...

pH dependence of the inhibition of yeast glyoxalase 1 by prophyrins

Hyperimmune lipopolysaccharide antiserum mediated inhibition of the adherence of E. coli O157:H7 to HEP-2 cells and large intestine of mice

Escherichia coli O157:H7 is found in cattle farms and can live in the intestine of healthy cattle. Mostcases of human illnesses including nonbloody diarrhea, hemorrhagic colitis and hemolytic uremic syndromecan be traced, either directly or indirectly, to cattle. One strategy for reducing the risk of EnterohemorrhagicEscherichia coli (EHEC) infections in human is to reduce the prevalence of inf...

Differentiation of M. scrofulaceum from Related Mycobacterial Species by Double-Diffusion Technique

Isolation and differentiation of various species of mycobacteria are predominantly based on conventional, cultural and biochemical tests. Among the non-tuberculous mycobacteria, these tests are unable to differentiate M. scrofulaceum from M. avium-intracellulare (MAI) because of their identical biochemical characteristics. For this reason, one hundred mycobacterial strains suspected to be M. ...
