Properties of the amino acids


The 20 common amino acids are (with 3 letter and 1 letter abbreviations):

Alanine (Ala, A)

chem


Arginine (Arg, R) ("aRginine")

chem


Asparagine (Asn, N) ("asparagiNe," "aspartic-NH2")

chem


Aspartate (Asp, D) ("asparDic acid")

chem


Cysteine (Cys, C)

chem


Glutamate (Glu, E) ("glutEmic acid")

chem


Glutamine (Gln, Q) ("Qutamine")

chem


Glycine (Gly, G)

chem


Histidine (His, H)

chem


Isoleucine (Ile, I)

chem


Leucine (Leu, L)

chem


Lysine (Lys, K) ("K" next to "L")

chem


Methionine (Met, M)

chem


Phenylalanine (Phe, F) ("Fenylalanine")

chem


Proline (Pro, P)

chem


Serine (Ser, S)

chem


Threonine (Thr, T)

chem


Tryptophan (Trp, W) ("tWiptophan")

chem


Tyrosine (Tyr, Y) ("tYrosine")

chem


Valine (Val, V)

chem


Ambiguity codes and Modification codes

Asx, B ("B" near "D")

Either Aspartic acid or Asparagine, uncertainty due to hydrolysis.


Xle, J ("J" between "I" and "L")

Either Isoleucine or Leucine, ambiguity from Mass spec data

Xaa, X

Unknown amino acid

Glx, Z ("Z" near "X")

Either Glutamic acid or Glutamine, uncertainty due to hydrolysis

Sec, U

Selenocysteine (Uniprot uses C and a feature rather than U)

Pyl, O ("pyrrOlysine")

Pyrrolysine (Uniprot uses K and a feature rather than O)
