DNA polymerase eta M-CSA #975 | DNA polymerase eta is a translesion synthesis (TLS) polymerase. The TLS polymerases are an important part of the DNA synthesis pathway which aid in resistance to DNA damage. They are crucial in overcoming DNA damage in cells by bypassing DNA damage lesions during DNA replication, which may otherwise stall the replication fork and lead to cell death. Eta polymerases are of interest because when mutated, can lead to cancer and are implicated as causes of antibiotic and chemotherapy resistance. | Defined by 9 residues: ASP:A-16 [auth A-13]MET:A-17 [auth A-14]TYR:A-55 [auth A-52]ARG:A-58 [auth A-55]ARG:A-64 [auth A-61]SER:A-116 [auth A-113]ASP:A-118 [auth A-115]GLU:A-119 [auth A-116]LYS:A-234 [auth A-231] | EC: 2.7.7.7 (PDB Primary Data) |
