However, in that study, cystine was also added to the control medium.
Since cystine signals were obtained from all peptides on both composition and sequence analyses, the two were considered to be cysteine residues.
Low contents of cystine were detected during fertilisation but cysteine and -glutamylcysteine were not detected in any treatment groups.
The subunit similarity is at its highest in the area of the cystine knot.
The disulfide -cross : from cystine geometry and clustering to classification of small disulfide rich protein folds.
In the present study we detected relatively low levels of cysteinylglycine and cystine.
It is likely that both cystine and glycine produced from cysteinylglycine by the activity of dipeptidases may be used for protein synthesis in zygotes.
Elemental sulphur or cystine is required for growth and reduced to hydrogen sulphide1,2.
Furthermore, in the present study we could not detect cysteine and -glutamylcysteine although cystine was detected in equal amounts among treatment groups.
Cysteine is unstable and easily oxidized to cystine in the medium.
Cys and/or cystine were added to the control medium.
Mechanisms of cysteine and cystine uptake into porcine oocytes matured in culture.
Human hair and skin contain approximately 10-14% cystine by mass.
