Summary
-
1)
Unidirectional transmembrane transport of3H-lysine across the mucosal border of the midgut from the freshwater shrimp,Macrobrachium rosenbergii, has been examined using an in vitro perfusion procedure.
-
2)
Influx of this amino acid appeared to take place through a high-affinity, carrier-mediated transport system displaying Michaelis-Menten kinetics (Kt=18.0±2.1 μM;J maxmc =0.50±0.06 nm/g min) and an apparent low-affinity mechanism that had a transfer rate which was a linear function of luminal lysine concentration. The latter system cannot be conclusively distinguished from simple diffusion at this time.
-
3)
The high-affinity process was sodium-dependent (lithium adequately substituting for sodium) and inhibited by arginine and iodoacetic acid.
-
4)
The apparent low-affinity transport mechanism displayed homoexchange diffusion and was sodium-independent, inhibited by arginine and unaffected by iodoacetic acid.
-
5)
Entry of lysine by either process was unresponsive to NaCN, ouabain and alteration of luminal pH.
-
6)
These results suggest that cationic amino acid influx in crustacean intestine appears similar to processes reported for these solutes from a large variety of cell types. The major difference found for the shrimp gut is the apparent adaptation of the high-affinity carrier process for very low lysine concentrations.
