Structural highlights

3q7r is a 2 chain structure with sequence from Chlamydia trachomatis 434/Bu. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.

Function

CHXR_CHLT2 May be a global positive regulator of transcription (PubMed:21057008). Binds a cis-acting element of its own promoter DNA sequence and is hence probably also involved in its own transcription activation (PubMed:21057008, PubMed:21775428, PubMed:24646934). The recognition sequence is 5'-WHGAWNH-N(3-5)-WHGAWNH-3', where W is A/T, H is C/A/T, N is G/C/A/T and the linker length in the middle is 3 to 5 nucleotides (PubMed:21057008).[1] [2] [3]
