The annotation and conditions in this rule are derived from the following entries: P0A7G6 (RECA_ECOLI), P9WHJ3 (RECA_MYCTU)

If a protein meets these conditions... i

Common conditions

    • Matches HAMAP signature MF_00268
    • taxon = Bacteria
    • fragment ≠ the sequence is fragmented

Special conditions

    • Subsequence at position 67 - 74 aligns to "G-x-E-S-[GS]-G-K-T" in entry P0A7G6

... then these annotations are applied i

Protein namei

  • Recommended name:
    Protein RecA
    Alternative name(s):
    Recombinase A

Gene namei

  • Name:recA

Subcellular locationi


  • Can catalyze the hydrolysis of ATP in the presence of single-stranded DNA, the ATP-dependent uptake of single-stranded DNA by duplex DNA, and the ATP-dependent hybridization of homologous single-stranded DNAs. It interacts with LexA causing its activation and leading to its autocatalytic cleavage.

Sequence similaritiesi

Nucleotide bindingi

  • ATP (to residues corresponding to positions 67 - 74)
