A single SHMT monomer can be subdivided into three domains: an N-terminus “arm,” a “large” domain, and a “small” domain. The N-terminus arm appears to maintain the tight interaction between two monomers. The arm, consisting of two alpha helices and a beta sheet, wraps around the other monomer when in oligomeric form.
