  The analogs of Chevalley generators are offered for simple (and close to
them) Z-graded complex Lie algebras and Lie superalgebras of polynomial growth
without Cartan matrix. We show how to derive the defining relations between
these generators and explicitly write them for a "most natural"
("distinguished" in terms of Penkov and Serganova) system of simple roots. The
results are given mainly for Lie superalgebras whose component of degree zero
is a Lie algebra (other cases being left to the reader). Observe presentations
of exceptional Lie superalgebras and Lie superalgebras of hamiltonian vector
fields. Now we can, at last, q-quantize the Lie Lie superalgebras of
hamiltonian vector fields and Poisson superalgebras.
