There were two typos and one formatting error in Table 1, which originally appeared as follows:

Table 1.

Relative intrinsic reactivity (R_i) of 20 amino acids

Cysa	Metb	Trp	Tyr	Phe	His	Leuc	Ilec	Arg	Lys
29.2	20.5	17.4	12.0	11.2	10.0	9.3	4.4	2.9	2.2
Val	Thr	Ser	Pro	Glu	Gln	Asn	Asp	Ala	Gly
1.9	1.6	1.4	1.0	0.69	0.66	0.44	0.42	0.14	0.04

Table 1 appears correctly below and has been corrected in the online article. (Changes are highlighted in bold. Note that the line within the table is now in the middle.)
