title: Cross-linking analysis of the two forms of protein I, a major outer membrane protein of Escherichia coli.
abstract: The two forms of protein I were cross-linked to molecules of the same species, even when both were present simultaneously. This suggests that they form separate multimers in the outer membrane.
