If you eat a vegan diet high in grains and low in legumes, or eat foods high in L-Arginine and low in L-Lysine, then will you probably not get the amount of L-Lysine you need. This post is very quickly put together but I encourage you, especially if you want to be successful on the vegan diet or a near vegan diet, to read it and learn, learn, learn!
L-Lysine is a necessary building block for all protein in the body. L-Lysine plays a major role in calcium absorption; building muscle protein; recovering from surgery or sports injuries; and the body's production of hormones, enzymes, and antibodies. http://www.bodybuilding.com/fun/southfacts_lysine.htm
Here are the sources of Lysine according to BodyBuilding.com. They are really, really knowledgeable about protein:
Brewer's yeast, legumes, dairy, fish, and meat all contain significant amounts of lysine. Most people, including vegans (vegetarians who also avoid dairy and eggs), consume adequate amounts of lysine. Athletes involved in frequent vigorous exercise have an increased need for essential amino acids.
http://www.bodybuilding.com/store/lysine.htmlQuinoa is a great source of lysine. Here are some other sources and information about lysine

Legumes, quinoa, and pistachios are the only plants foods high in the amino acid lysine. If you are not eating them every day, you might be falling short of lysine needs. Read more at JackNorissRD.com.
The best bet, since legumes is up there on the list at VeganBodyBuilding.com no less, combine your beans and rice to get a complete amino profile or eat beans on the same day as you eat the grains.
Lysine Info:
-Lysine controls herpes virus and outbreaks.
-Lysine is a precursor to carnitine
-can boost human growth hormone.
-can reduce Lipoprotein (a) and protect from heart disease.

Dietary supplementation with an essential amino acid L-lysine has been shown to reduce chronic anxiety in humans with low dietary intake of L-lysine. A combination of L-lysine and L-arginine has been documented to normalize hormonal stress responses in humans with high trait anxiety. The present study was carried out in one hundred eight healthy Japanese adults. The aim of study was to find out whether a week-long oral treatment with L-lysine (2.64 g per day) and L-arginine (2.64 g per day) reduces trait and stress-induced state anxiety and basal levels of stress hormones. We confirmed that, without regard to gender, the amino acid treatment significantly reduced both trait anxiety and state anxiety induced by cognitive stress battery. In addition, we found that the treatment with L-lysine and L-arginine decreased the basal levels of salivary cortisol and chromogranin-A (a salivary marker of the sympatho-adrenal system) in male subjects. These results of this double-blind, placebo controlled and randomized study confirm the previous findings in humans and animals and point to a combination of L-lysine and L-arginine as a potentially useful dietary intervention in otherwise healthy humans with high subjective levels of mental stress and anxiety.

Lysine is a limiting amino acid in diets based on wheat as the staple. In experimental animals, prolonged dietary lysine inadequacy increases stress-induced anxiety. If observed in humans, such a result would have a strong implication for the relationship between nutrition and communal quality of life and mental health. As part of a 3-month randomized double-blind study, we tested whether lysine fortification of wheat reduces anxiety and stress response in family members in poor Syrian communities consuming wheat as a staple food. In the lysine-fortified group, the plasma cortisol response to the blood drawing as a cause of stress was reduced in females, as was sympathetic arousal in males as measured by skin conductance. Lysine fortification also significantly reduced chronic anxiety as measured by the trait anxiety inventory in males. These results suggest that some stress responses in economically weak populations consuming cereal-based diets can be improved with lysine fortification.

GABA, the (benzo-like) inhibitory neurotransmitter requires adequate Lysine in order for its conversion from GABA's precursor - Glutamate - to take place.
And to quote a poster on a muscle mass forum, one who likely eats meat:
This makes me wonder. What is happening to our food? We seem to be deficient in everything. We're not getting enough magnesium, taurine, thiamin...Lysine? The list goes on....
Scroll down on this page
http://www.traditionaloven.com/tutorials/l-lysine_amino_acid.html and find the list that is titled "
Food containing high L-lysine and low L-arginine quantity amount". When you see the list, which is mostly fish at top of the list, then you will see why people who become ex-vegan crave fish if their vegan diet is not filled with sources of L-Lysine.
SOOOO, that's why it's been traditional to combine the grains and the beans. I will go back in time and say "I WAS WRONG" it's better to combine.
