Identification and function of selected 2-D gel protein spots that were down-regulated after 6 h of attachment time^a

Spot	N-terminal sequence	Locus	Protein	Protein description	Function
A8	MLIVTKNPPVVGHDQ	PA3623	NIpD	Outer membrane lipoprotein	Cell wall
A6	DDKVLHVVN-D–A	PA0300	PotF2	ABC transporter	Polyamine transport
B9	DVKIGVAGPMTDA	PA4913	NIb	ABC transporter	Amino acid metabolism
B2	KEAETVQKLANVVIL	PA1337	AnsB	Glutaminase asparaginase	Amino acid metabolism
A4	SAEKQK-GVHSEAGK	PA5171	ArcA	Arginine deiminase	Amino acid metabolism
A7	AFNIHNRNLL	PA5172	ArcB	Ornithine carbamoyltransferase	Amino acid metabolism
B1	MFSRDLTIAK-DA-L	PA4602	GlyA3	Serine-hydroxymethyltransferase	Amino acid metabolism
B4	-PATK-P	No match
B3	PATA-PAGKN	No match
A5	AD-IKI-GAQ-QD	No match

^aThe protein spots were N-terminally sequenced, and the proteins were identified by comparing the N-terminal amino acid sequence to that found on the P. aeruginosa website using the BLASTX program (1). The spot numbers correlate with the numbers indicated in Fig. 3. The locus designates the gene number in the genome of P. aeruginosa. 

^bNI, not identified.
