YozE-like is a family of Firmicute proteins that carries a four-helix motif similar to sterile alpha motif (SAM) domains. The family is suggested to fall into two subfamilies, possibly with differing functions based on the different surface charges on the three structural representatives, YozE MW0776 and MW1311. What this function is is not yet known although it is likely to involve binding to DNA [1].
