||A survey of E. coli proteins in the A survey of E. coli proteins in the SWISS-PROT annotated protein sequence databank (http://expasy.org/sprot/) is included in table 1. See note under table.
||This survey includes soluble proteins, membrane-bound proteins, and structural proteins. Monomers are in the minority, composing only about one fifth of the protein species. Dimers and tetramers are far more common. Homooligomers also predominate: 79% of oligomers with from 2 to 12 subunits are homooligomers, whereas only 21% form heterooligomeric complexes.
