Figure 5.
Sequence alterations in the cin5 and eto2 alleles of the ACS5 gene. The putative TATA box is indicated (from ref. 42). Both indicated Ser residues are highly conserved in the aminotransferase superfamily to which ACC synthase enzymes belong. The insertion in eto2 is a C (on the coding strand) at the indicated position that is predicted to disrupt the carboxy-terminal 12 amino acids.
