Protein attributes

Sequence length	82 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Cofactor	Binds 1 zinc ion per subunit Potential.
Subunit structure	Component of the small ribosomal subunit. Mature ribosomes consist of a small (40S) and a large (60S) subunit. The 40S subunit contains 32 different proteins (encoded by 56 genes) and 1 molecule of RNA (18S). The 60S subunit contains 46 different proteins (encoded by 81 genes) and 3 molecules of RNA (25S, 5.8S and 5S). Ref.2
Subcellular location	Cytoplasm.
Post-translational modification	The N-terminus is not modified.
Miscellaneous	There are 2 genes for S27 in yeast.
Sequence similarities	Belongs to the ribosomal protein S27e family.
