Differences from the Standard Code:
None

Alternative Initiation Codons:
GUG, UUG, AUU, CUG

Systematic Range:
Prokaryotes including the eubacteria (Kozak, 1983) and archaebacteria (Brown et al. 1989; Noelling et al., unpublished).

Comments:
UGA codes at low efficiency for Trp in Bacillus subtilis and, presumably, in Escherichia coli (Hatfiled and Diamond,1993).

CUG is known to function as an initiator for one plasmid-encoded protein (RepA) in Escherichia coli (Spiers and Bergquist, 1992) and possibly in Methanobacterium thermoautotrophicum (Noelling et al., unpublished)

There is no record of AUU initition codon for the archaebacteria.
