The GenBank accession number corresponds to the gene sequence used in the construct. The coordinates of the cloned fragment are shown. CTG codons were changed to TCT using site-directed mutagenesis so that a native C. albicans amino acid sequence would be produced in P. pastoris. The number of codons that were changed is specified, as well as their position within the cloned sequence.
Proteins produced in P. pastoris used the native C. albicans secretory signal sequence, which was cleaved upon export, resulting in the mature protein with the amino acid coordinates shown. N-linked glycosylation was present on four of the Als N-terminal proteins and was removed using Endoglycosidase H as indicated.
