- * Ribosomal protein S4e signature *
- ***********************************
-
- A number of eukaryotic and archaebacterial ribosomal proteins can be grouped
- on the basis of sequence similarities. One of these families consists of:
-
- - Mammalian S4 [1]. Two highly similar isoforms of this protein exist : one
- coded by a gene on chromosome Y, and the other on chromosome X.
- - Yeast S7 (YS6).
- - Halobacterium marismortui HS3 [2].
- - A probable ribosomal protein (ORF C) from Methanococcus vannielii [3].
-
- These proteins have 233 to 262 amino acids. As a signature pattern, we
- selected a highly conserved stretch of 15 residues in their N-terminal
- section. Four positions in this region are positively charged residues.
-
- -Consensus pattern: H-x-K-R-[LIVM]-[SA]-x-P-x(2)-W-x-[LIVM]-x-[KR]
- -Sequences known to belong to this class detected by the pattern: ALL.
- -Other sequence(s) detected in SWISS-PROT: NONE.
