cCMP and cUMP stimulate the acid phosphatase activity of AphA in Haemophilus influenzae

The paper investigates the effects of cyclic CMP and UMP on AphA's acid phosphatase activity in Haemophilus influenzae, finding stimulation rather than inhibition.

Substrate promiscuity of the Escherichia coli xanthine oxidase

The paper quantifies the substrate promiscuity of Escherichia coli xanthine oxidase by showing it can use guanine as a substrate, expanding its known metabolic role.

Escherichia coli acid phosphatase AphA expression is upregulated under carbon and phosphate starvations and inhibited by CytR

This study shows that E. coli aphA expression increases under carbon and phosphate starvation but decreases with CytR, indicating CytR's repressive role.

Cyclic AMP competitively inhibits periplasmic phosphatases to coordinate nutritional growth with competence development of Haemophilus influenzae

This study shows cAMP competitively inhibits periplasmic phosphatases in H. influenzae, linking nucleotide utilization to competence development.
