- * DnaA protein signature *
- **************************
-
- The bacterial dnaA protein [1,2,3] plays an important role in the initiation
- and regulation of chromosomal replication. DnaA is an ATP- and DNA-binding
- protein. It binds specifically to 9 bp nucleotide repeats known as DnaA boxes
- which are found in the chromosome origin of replication (oriC).
-
- DnaA is a protein of about 50 Kd that contains two conserved regions: the
- first one is located in the N-terminal half and corresponds to the ATP-binding
- domain; the second is located in the C-terminal half and could be involved in
- DNA-binding. We have used the most conserved part of the putative DNA-binding
- domain as a signature pattern.
-
- -Consensus pattern: I-G-x(2)-[LIVMF]-[SG]-G-[KR]-x-H-[ST]-T-[LIVM](2)-x-[SA]-
- x(2)-[KR]-[LIVM]
- -Sequences known to belong to this class detected by the pattern: ALL.
- -Other sequence(s) detected in SWISS-PROT: NONE.
