DNA topoisomerase I; Releases the supercoiling and torsional tension of DNA, which is introduced during the DNA replication and transcription, by transiently cleaving and rejoining one strand of the DNA duplex. Introduces a single-strand break via transesterification at a target site in duplex DNA. The scissile phosphodiester is attacked by the catalytic tyrosine of the enzyme, resulting in the formation of a DNA- (5'-phosphotyrosyl)-enzyme intermediate and the expulsion of a 3'-OH DNA strand. The free DNA strand then undergoes passage around the unbroken strand, thus removing DNA supe [...]

DNA polymerase I (POL I); In addition to polymerase activity, this DNA polymerase exhibits 5'-3' exonuclease activity.

30S ribosomal protein S21; Belongs to the bacterial ribosomal protein bS21 family.

30S ribosomal protein S10; Involved in the binding of tRNA to the ribosomes. Belongs to the universal ribosomal protein uS10 family.

50S ribosomal protein L31; Binds the 23S rRNA; Belongs to the bacterial ribosomal protein bL31 family. Type A subfamily.

30S ribosomal protein S9; Belongs to the universal ribosomal protein uS9 family.

50S ribosomal protein L33; Belongs to the bacterial ribosomal protein bL33 family.

30S ribosomal protein S18; Binds as a heterodimer with protein S6 to the central domain of the 16S rRNA, where it helps stabilize the platform of the 30S subunit; Belongs to the bacterial ribosomal protein bS18 family.
