Contents

HMGD(M13A)-DNA complex

Template:ABSTRACT PUBMED 20800069

Function

[HMGD_DROME] Binds preferentially single-stranded DNA and unwinds double stranded DNA. Prefers sites containing the sequence 5'-ttg-3'. Facilitates DNA bending. Associated with early embryonic chromatin in the absence of histone H1.[1] [2] [3]

About this Structure

3nm9 is a 16 chain structure with sequence from Drosophila melanogaster. Full crystallographic information is available from OCA.
