6.3.5.4 | Br- | strong activation of Asn synthesis and Gln hydrolysis. The synthetase reactions with NH3 or NH2OH are only slightly stimulated | Lupinus luteus | |
6.3.5.4 | Cl- | strong activation of Asn synthesis and Gln hydrolysis, competitive activator with respect to Gln and a noncompetitive activator with respect to MgATP2- and Asp. Cl- changes the substrate saturation kinetics of Gln from negatively cooperative to normal hyperbolic and causes a 50fold increase in the affinity for Gln. Inherent glutaminase activity is enhanced 30fold. The synthetase reactions with NH4+ or NH2OH are only slightly stimulated | Lupinus luteus | |
6.3.5.4 | CN- | stimulates Asn synthesis and Gln hydrolysis | Lupinus luteus | |
6.3.5.4 | F- | stimulates Asn synthesis and Gln hydrolysis | Lupinus luteus | |
6.3.5.4 | I- | stimulates Asn synthesis and Gln hydrolysis | Lupinus luteus | |
6.3.5.4 | NO3- | stimulates Asn synthesis and Gln hydrolysis | Lupinus luteus |
