Structure of Mcm10 Protein (IMAGE) Vanderbilt University Caption Mcm10 is shown in a surface view interacting with a single strand of DNA (depicted in red). Mcm10 contains two classic binding scaffolds. One is an OB-fold (OB stands for oligonucleotide/oligosaccharide) shown in green. The other is a structure called a zinc finger shown in blue. Proteins typically use OB-folds to interact with single-stranded DNA, while zinc fingers are used normally to recognize double-stranded DNA segments.
