(Upper) Deduced amino acid sequence comparison of IPK
from peppermint (M.p.; AF179283), pTOM41 from tomato (L.e.; U62773), a
hypothetical protein from A. thaliana (A.t.; AC005168,
PID g3426035), IPK from E. coli (E.c.; AF179284), and a
hypothetical protein from Synechocystis sp. strain
PC6803 (Syn; D90899, PID g16665). CON indicates the consensus sequence.
Identical residues are black with white lettering, residues of high
similarity are indicated in gray, and residues of lower similarity are
in light gray. Asterisks indicate the position of the putative
ATP-binding motif, the putative cleavage site of the plastidial
targeting sequence is shown by an arrow, and a conserved insert in
bacterial sequences is underlined. (Lower) Comparison of
sequences of an ATP-binding site found in representatives of protein
kinases (PK), mevalonate kinases (MK), phosphomevalonate kinases (PMK),
homoserine kinases (HSK), galactokinases (GALK), and isopentenyl
monophosphate kinases (IPK).
