A PF07924 NuiA Nuclease A inhibitor-like protein Domain This family consists of protein sequences that are similar to the nuclease A inhibitor expressed by bacteria of the genus Anabaena ((NuiA, Swiss:Q44296). This sequence is organised to form an alpha-beta-alpha sandwich fold, which is similar to the PR-1-like fold. NuiA interacts with nuclease A by means of residues located at one end of the molecule, including residues making up the loop between helices III and IV and the loop between strands C and D. The mechanism of inhibition of nuclease A by NuiA is as yet incompletely understood [1]. PFAM PF07924
