Nucleotide change:

A5055341G

Amino acid change:

K28R | His3.3A-PA; K28R | His3.3A-PC; K28R | His3.3A-PD

Reported amino acid change:

K27R

Comment:

"The amino acid substitution ""K27R"" has been introduced into the endogenous His3.3A locus, rendering the residue non-modifiable. The K is actually the 28th amino acid since the initiator Met does not appear to be counted in the numbering. Site of nucleotide substitution in mutant inferred by FlyBase curator based on reported amino acid change."
