TABLE 2.

N-terminal sequences of peptides derived from cleavage of UspA1

UspA1 peptide sequencea	Matchb (residue no.)	Cleavage agent
LENNVEEPXLNLS	456–468	Lys-C
DQKADI	473–478	Trypsin
NNVEEGLLDLSGRLIDQK	504–521	Lys-C
	278–294*
VAEGFEIF	690–697	Trypsin
AGIATNKQELILQNDRLNRI	701–720	Lys-C

^aX denotes an unidentified amino acid residue; underlining denotes a mismatch with the nucleotide-derived amino acid sequence (2). 

^bAn asterisk indicates that the sequence also matches that sequence of UspA2; no asterisk indicates a match only with the nucleotide-derived amino acid sequence of UspA1.
