History |
| ||||||
Remark 999 | SEQUENCE THIS IS A SOLUBLE CONSTRUCT OF A MUTANT PBP 5, TERMED SPBP 5 TO PRODUCE SPBP 5, THE LAST ...SEQUENCE THIS IS A SOLUBLE CONSTRUCT OF A MUTANT PBP 5, TERMED SPBP 5 TO PRODUCE SPBP 5, THE LAST 17 AMINO ACIDS WERE REMOVED BY DELETION OF THEIR RESPECTIVE CODONS, AN ADDITIONAL SIX AMINO ACIDS (GDPVID) WERE INTRODUCED AT THE C TERMINUS DUE TO READ-THROUGH TO THE STOP CODON. NONE OF THESE NON-NATIVE RESIDUES ARE VISIBLE IN THE ELECTRON DENSITY MAP. THE FIRST 29 AMINO ACIDS OF THE PROTEIN ENCODED BY THE OPEN READING FRAME REPRESENT THE SIGNAL SEQUENCE, WHICH IS REMOVED DURING MATURATION AND TRANSPORT TO THE PERIPLASMIC SPACE AND IS NOT PRESENT IN THIS CONSTRUCT. |
