Disease relevance of PsaL

Growth and photosynthetic characteristics of a selected mutant strain under photoautotrophic conditions were similar to those of the wild type, suggesting that the function of PsaL is dispensable for photosynthesis in Synechocystis sp. PCC 6803 [1].

High impact information on PsaL

The deduced amino acid sequence is homologous to the subunit PsaL of barley photosystem I. There are two conserved hydrophobic regions in the subunit PsaL that may cross or interact with thylakoid membranes [1].

Analytical, diagnostic and therapeutic context of PsaL

Southern blot analysis indicates that PsaL is a single copy gene [2].
Northern blot analysis shows that the expression of the PsaL gene is light-induced similar to other of the barley photosystem I genes [2].
