   3.1.21.1 | DNA + H2O |
degradation of DNA from supernumerary spermatozoa which enter the ovum durig polyspermic fertilisation in birds |
| 3.1.21.1 | double-stranded DNA + H2O |
- |
| 3.1.21.1 | double-stranded DNA + H2O |
preference for double-stranded DNA |
| 3.1.21.1 | double-stranded DNA + H2O |
DNase I hypersensitive sites of chromatin near the 5'-ends of some genes, necessary for transcription by RNA polymerase II |
| 3.1.21.1 | double-stranded DNA + H2O |
preference for single-stranded and supercoiled DNA |
| 3.1.21.1 | double-stranded DNA + H2O |
major function is to inflict nicks during early stages of hydrolytic attack on DNA, participation in repair phenomena |
| 3.1.21.1 | double-stranded DNA + H2O |
double-strand scission obtained if affinity for the substrate is at a maximum in the presence of both Ca2+ and Mg2+, single-strand scission and changes in specificity are associated with suboptimal concentrations of Ca2+ |
| 3.1.21.1 | double-stranded DNA + H2O |
introduces preferentially breaks on the 5' side of dT |
| 3.1.21.1 | double-stranded DNA + H2O |
cutting one of the two strands by a nucleophilic attack on the O-3'-P-bond |
| 3.1.21.1 | double-stranded DNA + H2O |
involved in seed sprouting |
