Let
Λ
\Lambda
be an artin algebra or, more generally, a locally bounded associative algebra, and
S
(
Λ
)
\mathcal {S}(\Lambda )
the category of all embeddings
(
A
⊆
B
)
(A\subseteq B)
where
B
B
is a finitely generated
Λ
\Lambda
-module and
A
A
is a submodule of
B
B
. Then
S
(
Λ
)
\mathcal {S}(\Lambda )
is an exact Krull-Schmidt category which has Auslander-Reiten sequences. In this manuscript we show that the Auslander-Reiten translation in
S
(
Λ
)
\mathcal {S}(\Lambda )
can be computed within
mod
Λ
\operatorname {mod}\,\Lambda
by using our construction of minimal monomorphisms. If in addition
Λ
\Lambda
is uniserial, then any indecomposable nonprojective object in
S
(
Λ
)
\mathcal {S}(\Lambda )
is invariant under the sixth power of the Auslander-Reiten translation.
