You are an expert at identifying data availability statements in scientific text. A data availability statement describes where research data can be found or how it can be accessed.<|eot_id|><|start_header_id|>user<|end_header_id|>

Determine if the following text contains a data availability statement. Answer with 'yes' or 'no'.

Text: Cryo-electron microscopy densities were deposited in the EM
Data Base under the accession codes EMD-4147 and EMD-4148 for the EC and the free
monomer, respectively. Sub-tomogram average densities were deposited in the EM Data Base
under the accession codes EMD-4149. Model coordinates were deposited in the PDB under
the accession codes 5M3F and 5M3M for the EC and the free monomer, respectively.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
