Amino acid alignments of two representative FAS
domains. (A) FAS β-keto acyl synthase domain of the α
subunit. Ca, C. albicans (23); Sc, S.
cerevisiae (25); Pp, P. patulum (28); and FasA
and StcJ, A. nidulans. The constitutive FAS a peptides
share 78% identity within this domain in contrast to StcJ that shares
only 57% identity. (B) FAS malonyl/palmitoyl transferase
domain of the β subunit. Ca, C. albicans (22); Sc,
S. cerevisiae (24); Yl, Y. lipolytica
(26); and FasB and StcK, A. nidulans. The constitutive
FAS β peptides share 72% identity in contrast to StcK that shares
44% identity.
