Let pp be a fixed odd prime number. In this note we study the class of finite pp-groups GG admitting an automorphism φ{\varphi} of order 22 such that G=g1gφgGG=\langle \, g^{-1}g^{{\varphi} } \mid g \in G \, \rangle and (g1gφ)p=1(\kern 0.5pt g^{-1}g^{{\varphi} })^{\kern 1pt p}=1 for all gGg \in G. In this paper we prove that if the derived length of GG is dd and CG(φ)C_{G}({\varphi} ) is nilpotent of class cc, then the nilpotency class of GG is bounded by a function depending only on dd, cc and pp. We prove also that if p=3p=3 and CG(φ)C_{G}({\varphi} ) is nilpotent of class cc, then GG is nilpotent of class at most 2c+12c+1.
