The k and k /K values in the original publi- cat cat m IPHP 493 (28) 0.36 (0.02) 730 (31) cation were found to be incorrectly calculated, and these VvOMT2 IBHP 628 (29) 0.09 (0.002) 137 (3) have been corrected in the following table. The original IPHP 1,264 (120) 0.19 (0.01) 150 (10) values would have implied that the enzyme is inactive Standard error values are given in parentheses against the hydroxypyrazine substrates. The corrected table shows that the VvOMT1 and VvOMT2 enzymes have k cat values, when hydroxypyrazines are used as substrates, that suggest catalytic production of methoxypyrazines by these enzymes is possible.
