Staphylococcus aureus staphyloxanthin expression is not controlled by Hfq
View through CrossRef
ABSTRACT
Objective
The golden color of
Staphylococcus aureus
is due to the synthesis of carotenoid pigments. In Gram-negative bacteria, Hfq is a global posttranscriptional regulator, but its function in
S. aureus
remains obscure. The absence of Hfq in
S. aureus
was reported to correlate with production of carotenoid pigment leading to the conclusion that Hfq was a negative regulator of the yellow color. However, we reported the construction of
hfq
mutants in several
S. aureus
strains and never noticed any color change; we therefore revisited the question of Hfq implication in
S. aureus
pigmentation.
Results
The absence or accumulation of Hfq does not affect
S. aureus
pigmentation.
