ABSTRACT Adenylate cyclases (ACs) catalyze the formation of 3′,5′-cyclic AMP (cAMP) from ATP. A novel AC-encoding gene, cyaC , was isolated Rhizobium etli by phenotypic complementation an Escherichia coli cya mutant. The functionality gene corroborated its ability to restore cAMP accumulation in E. Further, overexpression a malE :: fusion protein allowed detection significant AC activity levels cell extracts CyaC is unrelated any known or other exhibiting currently function. Thus, represents...
Phosphate metabolism was studied to determine whether polyphosphate (polyP) pools play a role in the enhanced resistance against Cd2+ and metal-removal capacity of Cd2+-preadapted (CdPA) Methanosarcina acetivorans. Polyphosphate kinase (PPK), exopolyphosphatase (PPX) phosphate transporter transcript levels their activities increased CdPA cells compared control (Cnt) cells. K+ inhibited recombinant Ma-PPK activated Ma-PPX, whereas divalent cations both enzymes. Metal-binding polyP...
Eukarya pyruvate kinases possess glutamate at position 117 (numbering of rabbit muscle enzyme), whereas bacteria have either or lysine. Those with E117 are K+-dependent, those K117 K+-independent. In a phylogenetic tree, 80% the sequences occupied by T113/K114/T120 and 77% L113/Q114/(L,I,V)120. This work aims to understand these residues' contribution K+-independent using K+-dependent enzyme. Residues 120 crucial in differences between -independent mutants. activity increased L113 Q114 K117,...
