ACG act as an osmosensor, so spores formed from the acg- cells will germinate irrespective of the osmotic conditions.

The unit of s is seconds Most values of s are between 10-13 and 10-11 second. To
eliminate the exponents, the value of s is usually reported in svedbergs (S). 1 svedberg 10-13 second.

IF1 prevents tRNAs from binding to the portion of the small subunit that will become part of the A-site.

†IF2 is a GTPase that interacts with three key components of the initiation machinery: the small subunit, IF1, and the charged initiator tRNA (fMet-tRNAi f-Met). By interacting with these components, IF2 facilitates the association of fMet-tRNAi f-Met with the small subunit and prevents other charged tRNAs from associating with the small subunit.

† IF3 binds to the small subunit and blocks it from reassociating with a large subunit. Because initiation requires a free small subunit, the binding of IF3 is critical for a new cycle of translation.
