The Yeast column indicates whether or not there is a yeast homolog of the bacterial gene (Yeast). The notation is as follows: No (genes lacking a yeast homolog), Yes (genes with a yeast homolog that was not present in the microarray data), Yes* (genes with a yeast homolog that, although present in the microarray data, were not part of the 'cytoplasmic translation' cluster) and Yes** (genes with a yeast homolog that are found in the cluster)
