We describe a Gauss decomposition for the Yangian $$Y({\mathfrak{gl}}_{m|n})$$ of the general linear Lie superalgebra. This gives a connection between this Yangian and the Yangian of the classical Lie superalgebra Y(A(m − 1, n − 1)) (for m ≠ n) defined and studied in papers by Stukopin, and suggests natural definitions for the Yangians $$Y({\mathfrak{sl}}_{n|n})$$ and Y(A(n, n)). We also show that the coefficients of the quantum Berezinian generate the centre of the Yangian $$Y({\mathfrak{gl}}_{m|n})$$ . This was conjectured by Nazarov in 1991.
