So he's saying the number of proteins you COULD make from around 60 amino acids exceeds the Lloyd limit - not that there in fact is a Lloyd limit's worth of information stored in a given protein, brain, organism or even biosphere.
I'm not sure how significant that is. I mean, my hard drive could in principle store something like 2 ^ 4,500,000,000,000 possible combinations of bits, which is well above Lloyd's limit, but as far as I know it isn't alive.
