Table I.

Amino acid sequence and relative hydrolysis rates of newly synthesized substrates.

#	Peptide Substrate	Relative Hydrolysis Rate
c0	GSSKLQ	100.0
c1	GSSKLH	170.6
c2	GSSKLA	31.5
c3	GSSKYQ	256.9
c4	GSSKPQ	7.2
c5	GSSSLQ	52.6
c6	GSSALQ	43.2
c7	GSAKLQ	207.2
c8	GSSKLq	14.2
c9	GSSKlQ	10.7
c10	GSSkLQ	5.0
c11	GSsKLQ	103.8
c12	GsSKLQ	104.1

The peptide GSSKLQ (c0) was used as a reference to calculate relative hydrolysis rates. The single amino acid difference between a peptide and the reference sequence is indicated by bold Italic font at the corresponding position. The small underlined letter in c8–12 peptides indicates d-amino acid at that position.
