YecM bacterial protein domain
# YecM bacterial protein domain

In molecular biology, YecM refers to a protein domain found in Escherichia coli. It is a conserved, hypothetical protein with sequence homologues found exclusively in bacteria. Several bacterial YecM proteins in this particular family are of unknown function.

## Function

The precise function of the YecM domain remains to be elucidated. However, YecM structural homologues reveal that all the proteins bind a divalent metal cation. This comparison suggests that YecM may be a metal-binding protein and therefore may function as an enzyme.

## Structure

The protein domain, YecM, is a monomer. The eight, mostly antiparallel beta-strands form around C-terminal alpha-helix. There are four alpha helices in total.
