A family of proteins that were originally identified in SACCHAROMYCES CEREVISIAE as being essential for maintaining the structure of minichromosomes00. They form into a protein complex that has helicase activity and is involved in a variety of DNA-related functions including replication elongation, RNA transcription, chromatin remodeling, and genome stability.

A hexameric protein complex of minichromosome maintenance proteins.
