A number of new genes have been sequenced since worm codon usage was summarized by Emmons (Table 2 in The Genome, The Nematode Caenorhabditis ing Harbor Lab.). An updated codon usage table has been derived from the sequences of
act-1,
act-2,
act-3,
act-4 (Krause et al., J. Mol. Biol. 208 (1989) 381-392),
col-1,
col-2 (Kramer et al., Cell 30 (1982) 599-606),
col-6,
col-7,
col-8,
col-14,
col-19 (Cox et al., Gene 76 (1989) 331-344),
deb-1 (Barstead and Waterston, J. Biol. Chem. 264 (1989) 10177-10185),
dpy-13 (von Mende et al., Cell 55 (1988) 567-576),
glp-1 (Yochem and Greenwald, Cell 58 (1989) 553-563),
lin-12 (Yochem et al., Nature 335 (1988) 547- 550),
myo-1,
myo-2,
myo-3 (Dibb et al., J. Mol. Biol. 205 (1989) 603- 613),
