GO:0004520 endodeoxyribonuclease activity PMID:18281701 IDA: Inferred from Direct Assay F The T4 SegB protein is a site-specific endonuclease that recognizes a 27-bp sequence. 666 bp segB ORF was placed under the control of T7 promoter in pET-15b vector. SegB protein was overproduced in E. coli T7 lac promoter system and purified. The purified protein was incubated with a linear plasmid DNA and products were analyzed of the reaction through gel electrophoresis (Figure 3). SegB cleaved DNA by introducing double-strand breaks in reactions requiring Mg2+, Mn2+, or Ca2+ cations. With Mg2+ and Ca2+ cation, SegB cleaved the DNA at 1 point, creating 2.2 kb and 1.6 kb fragments. In the presence of Mn2+, multiple cleavage sites were present. complete

The comment was "there is a more specific GO term available". This typically means looking at your GO term (a molecular activity term) and seeing if there are more specific terms (children) that apply. Not changing it to a biological process term. I don't believe the paper provides support for such an specific claim.

There is a more specific GO term available.
