Alternative yeast nuclear code

The 'alternative yeast nuclear code (translation table 12) is a genetic code found in certain yeasts.

Alternative initiation codons

• CAG may be used in Candida albicans (Santos et al., 1993).

Systematic range

• Endomycetales (yeasts): Candida albicans, [[Candida cylindracea, Candida melibiosica, Candida parapsilosis, and Candida rugosa (Ohama et al., 1993).

Comment:

However, other yeast, including Saccharomyces cerevisiae, Candida azyma, Candida diversa, Candida magnoliae, Candida rugopelliculosa, Yarrowia lipolytica, and Zygoascus hellenicus, definitely use the standard (nuclear) code (Ohama et al., 1993).
