Studying
insulin
reveals some really cool
protein
motifs of
life
:
both the
A chain
and
B chain
are
transcribed
from
a
single
gene
. The resulting
peptide
also contain:
the
C-peptide
in the middle which gets removed
a
signaling
sequence
telling the
cell
to export the substance out
as
it is
a
hormone
