Function
function
Broad-specificity nucleoside monophosphate (NMP) kinase that catalyzes the reversible transfer of the terminal phosphate group between nucleoside triphosphates and monophosphates. Has also ATPase activity (PubMed:24823650).
Involved in the late maturation steps of the 30S ribosomal particles, specifically 16S rRNA maturation (By similarity).
While NMP activity is not required for ribosome maturation, ATPase activity is. Associates transiently with small ribosomal subunit protein uS11. ATP hydrolysis breaks the interaction with uS11. May temporarily remove uS11 from the ribosome to enable a conformational change of the ribosomal RNA that is needed for the final maturation step of the small ribosomal subunit (PubMed:24823650).

Catalytic activity
- AMP + ATP = 2 ADP
- ATP + H2O = ADP + H+ + phosphate
