Whey powder has a much better balance of amino acids than pea protein on its own.
Pea protein will—technically—supply you with a 'complete range' of amino acids, but is way too low in methionine, so ideally would be combined with grain protein, to compensate for that (on the rice and dal principle).

[Q]
what is your favorite amino acid and why?
[A]
Methionine because it is coded for by the start codon (AUG). It's the first amino acid of all polypeptide chains (prior to post-translational processing). Methionine is number 1!

Mass Spectrometric Analysis of Free Methionine Oxidation
Levels in E. coli
AbstractOxidation
of free methionine plays important roles in cellular
redox homeostasis, yet its accurate quantification has been hindered
by methodological challenges. Here, we introduce free methionine oxidation
by blocking (fMObB), a mass spectrometry-based method that enables
accurate measurement of the fractional oxidation of free methionines.
Applying fMObB to E. coli, we quantify
free methionine oxidation under basal and oxidative stress conditions
and in strains lacking methionine sulfoxide reductases. We found that
during oxidative stress, free methionines exhibit higher oxidation
levels than protein-bound methionines and that methionine sulfoxide
reductases play a central role in maintaining reduced free methionine
pools. Together, this work establishes fMObB as a generalizable strategy
for probing free methionine redox states in cellular systems.

When using limited amounts of seeds, we could see density for the methionine at position 337, confirming that we had indeed solved the structure of the seeded aggregates. However, we could also solve the structure of the seeds when using more seeds. This is an important warning for future studies.

Middle-Down Mass Spectrometry Characterization of

Identification and Quantification
AbstractCharacterizing
post-translational modifications (PTMs) in monoclonal
antibody products is critical for ensuring product quality attributes
understanding and monitoring. While the bottom-up approach is widely
adopted, it suffers from the loss of molecular connectivity and is
susceptible to artifact generation. Conversely, top-down approaches
face limitations due to the high complexity and poor gas-phase fragmentation
of large intact molecules to get site-specific post-translational
information profiling. Middle-down MS methods offer a complementary
middle-ground approach to both bottom-up and top-down, with broader
sequence coverage, and facilitate the simultaneous identification
of multiple attributes and proteoforms. In this study, we optimized
the electron-activated dissociation (EAD) approach for middle-down
sequencing of NISTmAb subunits and present a potential MS and MS/MS
strategy to rapidly characterize PTMs on antibodies, using methionine
oxidation as an example. Peroxide-stressed and control mAb samples
were digested and reduced into subunits using the IdeS enzyme and
analyzed via LC-MS, with the optimized MRMHR EAD method.
The resulting data enabled high-resolution subunit mass analysis,
sequence confirmation, and potential for site-specific oxidation localization.
Methionine oxidation localization in NISTmAb was achieved in light
chain (M4), Fd’ (M34, M101), and Fc/2 (M16, M122, M192), with
these locations confirmed with bottom-up peptide mapping data. Quantification
using the Fc/2 subunit enabled detection of oxidation levels up to
1% relative, with strong correlation (R2 > 0.99) between expected and observed values using MS1 data.
This
middle-down electron-activated dissociation (EAD) approach provides
a potential method for site-specific characterization of PTMs in antibody
products, offering valuable complementary mapping to support formulation
development and production.
