This entry represents the YcgR-like domain found at the N-terminal of MrkH (Swiss:G3FT00) from Klebsiella pneumoniae and similar sequences [1] which contain a PilZ domain at the C-terminal. MrkH is a c-di-GMP-related transcriptional regulator that affects type 3 fimbrial expression in response to cellular c-di-GMP level, playing and important role in biofilm formation. This protein binds to the promoter regulation fragments of mrkHI and mrkA mainly through its PilZ domain and this YcgR-like domain also participates in DNA-binding [1].	Domain
