L-threonine

1. L-threonine = acetaldehyde + glycine

Catalysed by SHMT1

1. L-threonine = 2-oxobutanoate + NH4(+)

Catalysed by SDS, SDSL

1. L-threonine(in) + L-glutamine(out) + Na(+)(out) = L-threonine(out) + L-glutamine(in) + Na(+)(in)

Catalysed by SLC1A5inner side of the membrane, outer side of the membraneOne of 4 routes

1. L-threonine = acetaldehyde + glycine

Catalysed by SHMT1

1. L-threonine(out) + L-alanine(in) = L-threonine(in) + L-alanine(out)

Catalysed by SLC7A10inner side of the membrane, outer side of the membraneOne of 4 routes

1. trans-4-hydroxy-L-proline(out) + L-threonine(in) + Na(+)(out) = trans-4-hydroxy-L-proline(in) + L-threonine(out) + Na(+)(in)
